auto save
Suppose you're editing a card and click "Cancel", or your browser crashes, or you leave or close the page without saving. Wagn will have saved what you're working on so that you can recover it later.
Examples
How To
When you're editing cards, a few times a minute Wagn saves a draft. If you never click "Save", then the draft remains available, and if you click on the card's Changes tab, you'll see something like this:
From there, click on "Autosaved Draft" to see the draft, and if you want to update the card to be that draft, then click on "Save as current".
Tips
As of Wagn 0.12, auto save works again but only when you're editing a single, existing card. It does not work when adding new cards, or when editing many cards at once (i.e., with content-formatted cards). It also doesn't work when adding comments.
