Hey, me again. Posted MerMark Editor here a while back — first post got 120+ GitHub stars and the binaries crossed 7 000 downloads, so thanks to everyone who tried it. Just shipped v0.2.0 and the diff is big enough that I think it's worth a fresh post. Pre-emptive disclaimer (so I don't have to argue in the comments) Yes, I know Obsidian exists.
