I’m so glad this thread exists.
When I’m in a .tsx tileset tab, I have to click the “Tileset” menu, then the “Tileset Properties…” item for the tileset properties to show up. The much more intuitive and convenient additional way to access this would be to click in the whitespace around the displayed tiles in the center. Currently, clicking on tiles shows the properties for those specific tiles, and clicking on the whitespace deselects all of them but still shows the properties for the last tile selected.
Another possible solution, which might be incompatible with the first one, is to not have the tileset properties window replace the existing tile properties window. Rather, have it pop up above or below it as a seperate window.
In either case, there should definitely be a button for the tileset properties window since there already is one for every other menu item in the “Tileset” menu.
Hope you liked my suggestion
