When you link alot of projects together, you get tons of tiles. Sometimes you want to build a fast map in Pro Motion just to see if the tiles work well with one another. What pains me is, that I usually have to turn of Sync-mode, otherwise I create tons of not needed tiles. And the moment I turn it on again, it also creates these not needed tiles, unless I have removed them before.
So my suggestion is: When you create a tileset project, you can activate the option to also create a second tab called “Creative Tab”. In this tab, sync-mode is always deactivated. You can place tiles freely, can create layers and get more options to be creative in this tab. No new tiles will be created here, no matter what.
This would help me alot to figure out if some tiles work well together or if I need to make adjustments.
