[autoconfig]

This is an awesome initiative! I'm using slate to build a web based flash card application that I'm hoping to release soon. It's been an absolute breeze to use as far as editor frameworks goes. I played around with a few others (draft, prosemirror) and while they have great out of the box experiences I found it very hard to incorporate a custom format and custom elements. Right now lack of android support is the only serious downside IMO. I will definitely be donating. Hope this goes well!
