So I recalled Arty's level creation stream:
https://www.youtube.com/watch?v=IsI9kSsZXlcHe still used the old editor as he has one major problem with the new format one and I can see that problem being a bigger issue for people using a lot of tileset mixing.
I personally haven't noticed it due to me sticking to 1 or 2 tilesets in most cases.
So the problem is: You have to constantly select and switch the tile selection bar for changing tilesets -- a huge problem when using many different tilesets and switching constantly.
I thought about a possible solution, but still I am not sure if making it standard or a selectable option would be better.
Proposed solution: Clicking on a tile changes the selection bar to the tile's tileset.
This would minimise the tileset selecting, as you would only need to select it once from the list, due to then having the option to click on a matching tile to switch. Also people who rarely use tileset mixing won't notice this due to them having only 1 active tileset most of the time.
Still I am wondering if making this an option under "Settings" would be a better call. If somebody does not like this behavior they simply can leave this deactivated.
I even would call this a higher priority, as this prvents people to switch to the new editor and they even take the extra step of converting for this.
So is my proposed solution acceptable? Is having this as an option better? Other proposals?
