Whoops, should have noticed your endorsement of syncthing before posting a comment mentioning this.

While Obsidian does save to individual files, the Markdown they use seems to be a superset of everyday Markdown. Eg, being able to use callouts (eg, Note, Warning, Info, etc) and embedded linking of notes.

The automatic backlinks are fantastic. And I’ve discovered that if I rename a note, all links to that note get updated as well. So no need to worry about orphaning pages.

I’ve added a handful of plugins as well. Off the top of my head, one is a dynamic table of contents (for that page), another helps to compose/edit Markdown tables.

Also a big fan of Obsidian!

For syncing, one option is to use syncthing.

I know someone (whose geek creds are admittedly well beyond mine) who is also a fan. He uses GitHub to sync his notes.

I learned it long ago as “catenate”.

Yep, seems to fit.
