i use obsidian notes and keep the files in a Dropbox folder that automatically syncs between my several devices. I use github pages to make it publicly visible. Since it’s on github, I’ve got all the benefits of version control and edit tracking. Also, other authors can use whatever markdown editor they want so long as they don’t break link formatting.
I made the jump to Linux a few months ago, and while there are certain conveniences that I miss, everything I actually need works fine. As for gaming, I don’t play anything with kernel level anticheat, so it doesn’t matter to me that those don’t work on linux.
