You're awfully curious, aren't you?
I use a mix of GSConnect/KDEConnect, Warpinator, and Syncthing. I've got a shared "dropoff" folder on Syncthing that lets me easily drop files from one device to another. You're having issues with Warpinator but if you're able to figure out the issue there, that's my second go-to for one-time file transfers. KDEConnect is a bit more fiddly, but I use it mostly for sharing clipboard info and the occasional file when it's stable enough.
Here's a few I've enjoyed in recent memory:
The Koyo album is great if you like punk/hardcore/emo, same with the Militarie Gun one. Tigers Jaw has been one of my favorites for a while, and this album is one of their best imo; great band if you like indie rock/emo. Yard Act's a British rock band with post-punk influences, you might like them if you enjoy that signature dry British humor in combination with some social commentary. Vacation Manor is a more laid-back indie rock band with more classic Americana/Springsteen influences, I can't recommend them enough for people who have a sweet spot for classic rock. Lastly, Hotline TNT's album is worth a listen for people who enjoy shoegaze and indie rock, they have a really great DIY sound with just enough polish to tie the album together and keep it accessible. The 2020's have been a damn good year for music, at least as far as the bands I've been keeping up with.
Edit: added Tigers Jaw, I couldn't leave them out
Can confirm Zorin has the best out-of-the-box process for getting Windows apps running. I have a family member that's really gotten attached to Zorin because of its familiar front-end, and even though they have some prior Linux experience from earlier years, they've never needed to use terminal knowledge for the basic stuff they've been using Zorin for.
This depends on if you installed Steam as a Flatpak or through the endeavourOS repositories, but one way that should work is editing the Exec line in the .desktop file. You've already tried that, but I don't know what you put there so it might be worth editing that line again. Try editing the Exec line to Exec=GDK_SCALE=2 /usr/bin/steam %U and let us know what happens.
There are dozens of us, dozens!
Not to be dramatic, but I think this means it's finally the year of the Linux desktop /s
Glad GNOME finally got this finished, it's good to finally have most of the major desktops on the same page with the freedesktop accent color support.
