lolpaca: They posted a preview of that on facebook actually! It's in the works, it seems!
As for suggestions,
- Apply Origin/Collision/Crop in Animation Folder
Sometimes I need to apply changes to an animations size, collision box, origin, image points, or whatever, but only to animations in a certain folder. It can get tedious to go through all of them sometimes, so this sort of thing would help.
-Vertex Painting/Texture Blending
In 3D, you can create non-tiled objects by having a base tiled texture, and then applying a second tiled texture on top and painting in the opacity. I imagine this would work very similarly to using layered imagemaps, but without being locked to a grid. Like if you combined tiled backgrounds, imagemaps, and the sprite editor.
I'm sure that's a lot easier said than done, but it would help a lot with creating unique levels that aren't tile-based.
