It'll be nice to have models that'll animate while level designing, or when pressing play instead of having to try to edit from game back to editor back to game. Also prefabs or even folders for level designing (in object list), that'll just select some objects because it gets complicated when having lots of models then not being able to rename/sort-in-list.

Except for those two thing it's been a smooth workflow, haven't crashed not once, compared to cryengine (where i thought crashing hourly was a given). every is intuitive on the coding side with all the tutorials, way easier to learn than others.
