Playing heaps of Kingdom Come: Deliverance at the moment, I have one set to toggle Up and B for autorun, and another to take a screenshot. I'm sure I'll find more uses the longer I have it.
I've been using Nobara and its been awesome. I wanted a fairly standard desktop with a gaming focus and it fit the bill. It even managed to automatically get the power saving sorted for my laptop which has a nvidia GPU. Great distro.
Haven't really been following it all - after reading the article I think maybe its because Astro Bot had a larger audience because its generally more accessible?
Thunderbird had this for so long, it was definitely something I noticed when having to use Outlook at work.
