There it is! I am with you 100%. All of these massive plugin systems are a giant time suck. You spend soooo much time just setting things up only to forget the little stuff you need to do when something breaks. Every plugin I have installed requires some level of configuration. The more feature rich plugins (with no surprise there) are basically apps in and of themselves.

I keep hearing praise about this being a simple app, but I found it to be very fiddly if you want more than just markdown rendered in your editor. Lots and lots of time to get things working/configured.

Sync has been a massive PITA for me with Obsidian. Unless you are willing to pay, there is going to be pain there eventually. I had similar problems with OneNote, but those sync problems have mostly disappeared. Further, OneNote's handwriting experience is really good. It is very easy to export all notes from OneNote to Markdown with Pandoc, so while I may be "locked" in, I can "get out" if I want.

Edit: So thank you Obsidian for helping me convert my notes in OneNote to markdown to try you out! I now have a verified escape hatch if I should ever need it. However, I am not sticking around. Too much trouble for little stuff and OneNote is just a really good all arounder.
