Nice, that's a big differentiator! I use git sync with my mobile vault, but it's very hacky (using a Termux cronjon) and it's often flaky. Plus I have to open up Termux any time I need to troubleshoot, which is a bit annoying.
I've been using plain git with a git server to sync several machines even though I have to execute a script to do it in each machine. If you see the vault is just the workspace plus markdown files. I didn't know you could add plugins to obsidian. This is interesting. I do wonder if this can be added to mobile - Android/iOS.
Mine doesn't use any script that you must run on each machine.
It uses the GitHub APIs to sync, so it works seamlessly on desktop and mobile. I'm actively using it both on my Mac, Windows machine and iPhone with no issues.
