Bearblog has plugins now!
I've been wanting a version history of sorts in bearblog post editor for a while now, mostly because I have a lot of drafts and I do not want to lose any progress there.
And it's finally here. And it's just a script you can write yourself. That's really cool!

Here's the version history plugin in action.

And I made a plugin to paste url as markdown link when creating posts for myself.
Thanks Herman!
