I think Steve Lemay is a good guy. I kind of fought with him when I was an engineer, he was a young, new designer (at Apple). But I always respected his point of view—even when we argued.When Jobs came back to Apple in the latter 1990's "Design" slowly came to have an outsized role. I was one half of the engineering team that owned Preview (the application) when Steve Lemay became a seemingly regular presence in the hallway. As the new "Aqua" UI elements arrived in the OS like the "drawer" and toolbar, Steve and his boss (forgetting his name right now—Greg Somebody?) were often making calls about our UI implementation.
The bigger argument I remember with Steve revolved around the drawer UI element. With regard to PDF's, (the half of Preview that I worked on, another engineer handled images), the drawer was to display thumbnails for each page. If the PDF had a TOC (table of contents) the drawer is where we would display that as well.
So when you opened a PDF in Preview, the PDF content of course would appear in the large window—thumbnails, TOC (later search) would be relegated to a vertical strip of drawer real estate alongside the window—the user could open/close the drawer if they liked to focus perhaps on the content.
Steve Lemay insisted the drawer live on the right side of the window [1]. This was inexplicable to me. I saw the layout of Preview as hierarchical: the left side of the content driving the right side. You click a thumbnail on the left (in the drawer) the window content on the right changes to reflect the thumbnail clicked on.
Steve said, no, drawer on the right.
"Why? Why the hell would we do that?"
Steve was quick: "The Preview app is about the content. The content is king."
I admit that I still disagreed with him after the exchange, but I had a new respect for him as a designer because he was able to articulate a rationale for his decision. I suppose I was prejudiced to expect hand-waving from designers.
(Coda: some years later after I had left the Preview team, an engineer still on the app let me know that the thumbnails, etc, were at last moving to the left side of the app. The "drawer" as as a UI element had by this time gone away: resizable split-views were the replacement.)
(Addendum: Steve also invented the early Safari URL text field that also doubled as a progress bar. Instant hate from me when I saw it: it was as if the text of the URL you entered was being selected as the page loaded. So I'm old-school and Steve had some new ideas…)
[1] Localization was such that in countries where right-to-left was dominant, the drawer would of course follow suit.

That would be more encouraging if Apple under Tim Cook didn't suffer from bad UX that sounds good when put into words.Tim Cook and the other c-suite Apple execs have bad taste.
If they had better taste, they never would have approved text layout that automatically applies inconsistent kerning to squish long menu items into narrow spaces. It's a tasteless idea that sounds great when put into words.
Flat UI probably sounded brilliant as a spoken sales pitch: "We'll make the GUI honest, direct, elegant: the clarity of highway signage". In practice, the Scott Forstall era was both easier to understand, and prettier.
'Liquid Glass' probably sounded fantastic when put into words. Unfortunately, there are some implementations of a 'lickable' GUI that are tasteless.
Hope springs eternal for some people. I personally gave up on Apple shortly after SJ died.

I have a feeling what happened was that the C-Suite only watched a Keynote or live product demo that, like everything Apple presents to the public, was highly curated and scripted to win approval.

Suppose someone had just said, make it a preference in a checkbox whether it goes on the left or the right. Would these titans have just stopped arguing, turned on whoever made the suggestion, and destroyed them together?by hyperhello

Sounds like the road to checkbox hell. Not to mention the added costs of supporting both the code and users with varying setting combos.by stefanfisk

Generally, you're right about your first point. Apple (and perhaps all "designers") want to get it right, not leave it to the whims of the user.Even if you allow for both options, you can still have a long drawn out argument about what the default should be. (And then if you can agree on the default, the thought raises its head—maybe we ought to just go with that alone and keep it simple.)

There is at least room to hope that Lemay may be able to take a more nuanced, reasonable approach. Believing that Preview.app needs to be designed with the "content is king" mindset doesn't necessarily mean believing that "content is king" needs to be the top priority everywhere throughout the OS even to the detriment of usability. After all, Preview.app is a pretty extreme example: displaying content is its primary purpose and almost the sole purpose; its editing and annotation capabilities are minimal and far less frequently used than the core functionality of viewing PDFs and images.But even though I'm hopeful, I'm definitely not holding my breath for a quick turnaround and big mea culpa from Apple. I bought a new laptop last fall specifically to avoid using Liquid Glass for as long as possible.

“I admit that I still disagreed with him after the exchange, but I had a new respect for him as a designer because he was able to articulate a rationale for his decision.”Any competent designer gets really good at justifying their decisions. Everyone has an opinion about design and thinks that their taste is correct.
I’m glad I don’t have to deal with that on the software side.

> Steve Lemay insisted the drawer live on the right side of the window [1]. This was inexplicable to me.Makes some sense to me if, as I suspect, people tend to place their windows aligned to the left of the screen. If that’s the case, opening the drawer to the left of its container (the window) would require not sliding the drawer out, but sliding the window to the right to make room for the drawer.
I think that that’s a reason the drawer analogy doesn’t really make sense. Another is that the question “what do you store in a drawer?” certainly isn’t “page thumbnails and table of contents”. “Rarely used tools” or “spare paper” are better answers.

"…but sliding the window to the right to make room for the drawer."You're right about that. (You should be a designer, ha ha.)
I think the "solution" was that the drawer was open by default when a new document opened. Therefore the window was placed in a way that already allowed for the drawer width.

Wouldn't help if the user closes the drawer and moves it to the left - which users used to having apps to the left (and to a left to right reading culture) would.The main problem I see is the mouse pointer has reason to be on the proximity of the left side: the Apple menu is there, the most important dock elements (on a bottom dock) are there - or the whole dock for a left-placed dock), the menubar File, Edit, etc, and the most common icons for icon bar operations are there.
And if 'content is king', navigating the content (TOC, search, thumbnail) should also be king, not just the current viewing page.

Yeah, probably ultimately why the drawer disappeared in favor of the resizable split-view.by JKCalhoun

It's not a perfect equivalency but putting the drawer on the right side seems to be a bit inconsistent with their own Finder display (Show Items as Columns) where you drive from left-to-right with the right-most being a preview of a media asset such as a picture for example.But I wasn't an early user of MacOS, I don't know when this Column layout was first introduced.

If "left-hand" is king I wonder if they would have reversed the drawer's position for localization in countries with RTL languages.

Instead of the drawer on the side, NeXTSTEP had the Shelf on top: https://en.wikipedia.org/wiki/Shelf_(computing)

Thanks TIL. Tangentially related, I'm a huge fan of the aesthetics of the NeXTcube (even if by all accounts it was a bit of a nightmare to build from a engineering perspective).by vunderba

Love this kind of behind the scenes -- thanks for sharing!Personally, I think in a way you both ended up right. Content is king. But with the iPad (my favorite PDF viewer) as an important part of the Preview landscape now, I view the right side as where content should live.

That's a soundbite masking as a rationale that is really only "because I said so". He may have been right, there may have been more to it than this but if that's the extent? As another poster said, this kind of reflexive thought is part of Apple's current design challenges.
