Hey Jonathan, Thanks for the kudos, it's nice that this library is actually useful to people because I wrote it last year and it sat for a while.
I know you said you solved the problem you were having, I just figured I'd share a github repository of the prototype work I was doing on a UI Tree component in case you wanted to compare it to another idea. Again, I wrote this code a year ago so I don't know if it will be useful to you, but I was able to get a functioning UI tree that I was happy with. https://github.com/tomjkidd/elm/tree/master/practice/tree-work best, Tom On Tuesday, October 18, 2016 at 5:21:41 AM UTC-4, Jonathan Fishbein wrote: > > Actually might have gotten it to work!
