Talented people working on Intel GPU drivers sounds great.

In case you use GNOME it has keybinds you can map to console commands built in

apparently btrfs can get corrupted if it unexpectedly loses power?

What do you mean by that?

Corruption on power loss is something that journaling should prevent and modern filesystems do that. So btrfs should be as safe as other modern filesystems.

Edit: Btrfs does no journaling, it implements resilience with another mechanism, namely Copy on write.

You said you tried Apps from F-Droid, still FossWallet in F-Droid works good for me.
