i'm currently using it like a faux-fourth monitor that i can control if i move my mouse off the edge of my last normal monitor. it also locks and unlocks when i do the same on my computer
i also have a lot of pretty power-hungry tasker and termux stuff set up on it because it's gonna likely be perpetually plugged in from now on!
it also, by default, has my masto and birdsite timelines all combined, just casually scrolling by
this tablet (that i named "Android 17") was a freebie i got once, and was actually pretty dated at the time i got it
it still runs termux, tasker, and deskdock though!
i plan to have it scan for proximity of my phone (Android 18) and have it toggle a bunch of stuff based on that too, so certain things will only be active when i'm around
all this stuff was actually pretty fast to set up, because i've messed with tasker and termux a heck of a lot on my phone before
deskdock is newer, but since it's basically just "android synergy", there wasn't much of a learning curve outside of the initial "holy heck! this stuff is so much easier to do with my normal mouse and keyboard" (and the fact that it binds the "home" key to the home button, so i accidentally do that when typing a lot now ^^')
oh! and all this cool stuff? it turns off if i unplug it and puts the thing back into power-saving mode
so Android 17 basically turns back into a humble media/steam link tablet again with really good battery life
which consequently acts like a pretty handy switch that requires no real input to toggle..!
