It would be a great feature for those of us who have to create models with a lot of decals to have the ability to rearrange the order of the decals on a face.
Example: You have three decals on a face that all overlap and you need to make the bottom one (the first one applied) now sit on top of the other two decals. It would be nice to have the ability to right click on that decal and choose "Arrange > Move to Top/Front" or "Arrange > Move Forward/Back" etc. Similar to what Adobe Illustrator has.
(See attached screenshot)
And for advanced decaling, where you may have a smaller decal under bigger ones and not selectable, a window or something listing the bitmaps used and you can move the order using up/down buttons or something.
