I'd find it really useful if there were a tooltip showing the position of the tile on the map editor that the mouse is over if it hovers there for a while. 

I've ended up referencing tile locations to spawn objects in the games I've written in PixelBox and it would be convenient to not have to count how many tiles across / down I need to go by hand. I think the proposed Prop Layer in the roadmap would work just as well to address this, but thought it was worth suggesting!
