I don’t know why you chose to screenshot one of my garbage posts, but the rest of this seems pretty cool. Thanks for sharing!
I’ve done a little bit of reading about screen mirroring from Android to a desktop (using something like scrcpy) but haven’t yet taken the time to play with it. I don’t really like what Samsung does to the Android interface on their mobile devices (the “back” button should be on the left! 
), but what you’re showing here looks pretty cool, and I imagine it performs better than something like Waydroid, which I’ve tried on my PC (usually running Ubuntu LTS).
It’s too bad you can’t cross-categorize this, because it seems like a good Tips & Tricks thing. I don’t know if you can add the tips-and-tricks tag to its current category or not.
