Lightning Launcher

Probably the most customizable android launcher ever, and if all the different options and the canvas-like layout isn't enough, you can literally program it yourself with the included JavaScript engine interoperable with Java itself (Rhino).

Unfortunately the developer have been missing since the pandemic, and on android 12 has some minor issues. Still, I went back to it after feeling constrained with other launchers. This is the Arch linux of android launchers, the DIY master, and I'll probably keep using it until it no longer opens. When that happens...I'll really miss it.
