I use git for my Jekyll website, but not for my Dendron notes… I use my Dendron notes as a constant bullet journal / to do / "what am I doing right now" kind of thing, so I'm saving way more often than I'd remember to commit via git.
I've got a Dropbox plan that lets me more undo / version control than I think iCloud has, so it feels like it's got a safety net for my sync forgetfulness, on top of the safety net for file problems git offers.
