This is really nice, i tried it and everything i got to test yet works (mostly)!
- The debug lines are still active in some parts of the editor
- The fade in/out is looking good but the fade speed is annoyingly slow.
- Ninepatch tool :The bottom/right selectors (seem to) do nothing. A precise (input pixel coordinates) size selection would be practical
- Selecting an image to use in a field does not work after creating a new ninepatch or importing an image, it only works after changing tabs one or two times, refreshing resoruces does nothing
- Being able to set a different editor-background color would also be a nice feature to test dark skins
