Beautiful Tilemap in tool

I’d like to be able to organize the tilemap tools more flexibly, similar to what’s shown in the image, and have complete freedom to arrange them. For example, if I want a tilemap with 5 columns, I should be able to just type “5 columns” somewhere, and it would fix that configuration in the tilemap tools section. And, most importantly, when I organize my tiles, it shouldn’t replace or mess up the original file.

Currently, if I try to pick up a tile and move it in front of other existing tiles, Aseprite moves all subsequent tiles, which ends up messing up the entire artwork I’m using.
