I had a really shit ass redmi phone once which was cheap.The launcher was so slow and ass and had me wait for >10 minutes at times or be completely black which ate my god damn mind
Tried kiss launcher and it was beautiful and mostly worked like a charm on what it controlled
That being said, to manage wallpapers from kiss iirc atleast on redmi required me to do some crazy shenanigans which probably weren't worth it but none of them being kiss's fault.
I used to use nova launcher prior to kiss too and used to love nova launcher. Shame it went this path as I was seeing some kickstarter or change petition iirc to open source nova launcher which could've been so good.
On my other device I also use foss launcher which is a fork of simple-tools after it got accquired and all the issues which followed it (added ad tracking etc.)
Kisslauncher is so minimal like 300kb or something I forgot but extremely small iirc, it was wild to me to imagine an application this small. Might be smallest app I saw ever.
