All I know is that I’m in the same situation and the gmail mobile app works, so there’s something you can do.

I was gonna say, I tried it a couple months ago and I’m pretty sure it hadn’t been changed since when I was using it in like 2012. I thought a theme might help so I checked out the available themes, and the “popular” ones were ones that felt like they were from back then too. Everyone remembers Firefox / Thunderbird themes from back then: frosted glass, photos of space, flames, lots of gradients, themes that look like wood for some reason, that gross red text on black-white gradient background. It was like the entire app was aesthetically trapped in the early 2010s, even the community’s themes.

I’m sorry but the majority of people absolutely do not use more than one display.

I don’t have a gaming PC or anything, I just have a laptop, so ymmv, but performance in Linux, even of Proton games, is noticeably far better for me. Things are faster, I can crank the graphics settings up higher without lag, and my fan spins less angrily. Linux is just generally less resource-intensive than Windows by a very wide margin, so I think it leaves more for the game? Idk. All I know is it works better.
