@shilman , @usulpro
I've forked the react-treebeard, so now this branch is working without warnings. I would be glad to get the review =) (and merge)

[usulpro]

maybe it's worth to add some comments about new UI structure. I'd like to dig a bit this (and previous) PR so it could help to review

[shilman]

import { Treebeard } from ...

[igor-dv]

fixed

[shilman]

import { decorators } from ...

[igor-dv]

Yep.. But it didn't work (they changed the export of the index file in the PR) But I am changing it in the forked version to the named export and it should fix this.

[igor-dv]

fixed

[shilman]

@igor-dv i have some issues with the current state, but am merging/releasing anyway. i'll list them as separate issues that we can work through during the alpha stage
