I was wondering if there was a way to activate an app (flipclock) when I plug in the power. And possibly also close the app when I unplug the charging cable.

I tried searching, but I wasn't sure what I'm supposed to search for..triggers?

You can use "dbus-monitor" to see what events are triggered when charging, then use something like QBW (or whatever) to run whatever.

thanks I'll try that
