Project: Paper2D

Hey , just tried out Paper2D in 4.8 Preview 1 since Tilemaps got some love, and I immediately had a few things in mind to try out.
Fairly happy with how things work out (except a few quirks here and there that might be related to my setup, upper layers not blocking player in a top-down view for example), but I wanted to check first if you’re aware of any performance issues inside Tileset editor?
Over here it roughly takes a second from click to selecting/highlighting tile, and “Add Block” for collision has about same delay. It’s a 16x13 tile texture I grabbed off my old RPGMaker folder (256x256 px PNG) for testing, and I’m not sure what it will do if I put larger textures in there…
If is news to you guys, I can slap it onto AnswerHub with a small test project if you’d like.
