Hello, very nice tools !
I have a suggestion for the Auto-Layer rules assistant. To improve the QOL, as soon as we select an element it selects automatically the next one to fill in the template (left part). It's to avoid come and back at the selection of the template and then the associated tile (right part). And why not a hotkey to continue on the next tile model to fill (if there's nothing to select).
I adapted my tile format to LDtk but it's still a pain to fill :D
