automate installation of a list of apps

Not really. I'm sure you could set something up using fdroidcl or eget or something to grab apk's from Github, but nothing would be "automated."

Make a script using AutoHotkey (ask for help in ahk@programming.dev) that goes through the list in a Windows desktop browser and remotely installs the apps to the device one by one. That's how I'd do it, anyway.

If its a convenience thing. PI with shizuku can do background(in the notification) installs. So, you can tap install on multiple apks at the same time.
