Yeah I know, I miss it so much too. It was just the perfect app. Not trying to do too much, not too little, and really efficient at what it did. I could type out structured notes while on a call without even having to look at the screen. And finding them back was so much easier than in OneNote.

As I mentioned there is Tomboy-NG: https://github.com/tomboy-notes/tomboy-ng/releases/tag/v0.29 . It's a complete rewrite in a different language (Pascal with Qt).

It doesn't have the same ultra-fast feel of the old one though. And hyperlinks to other notes don't seem to update instantly like on the old one. I've tried it once but I never had that real "wow" feeling of the original.
