Nice job!

If you are comfortable with the command line, mbsync / isync allow you to save your mail offline with the ability to search and read it later on. You can use a cron job to fetch the email however often you want it.

That sombra nerf is insane. Not much utility anymore in her now, imho.

If you use emacs, you can set up gnupg integration for easy encryption and decryption of files.

I would also read up on expiration of keys, and how you can export (backup) and import a key. The latter can also be useful if you want to use the same key on multiple devices.

i just mean the one schizo mentioned

i have a 2017 lg 5k monitor (same goofy software trick) that works with ubuntu x11
