Great idea, just trying one out where you can import a GB Studio frame, drag to size and also make your own custom one out of tiles, seems to work pretty well, will add to the next release when ready.
I was just going to ask about terrain brush support, but this would nearly cover all my needs! Or at least make my process much, much easier... seeing as I can't seem to wrap my head around terrain brush setup in other programs... 😝 really happy to see cool new features already!
