Tree keyboard navigation

I think that the default tree keyboard navigation is kind of weird. There’s no default key to open or close a tree node and it forces you to use the mouse.
I found myself writing new handlers for tree keyboard event instead of using the default option so that the right and left arrows open and close the selected tree node:

Could you implement something similar as the default tree keyboard navigation?
Thanks

Yep, currently keyboard navigation in tree uses the same logic as for plain list.
We will include the open|close branch behavior in the next update

Thanks for suggestion
