This will sound pretty simple but selecting a decal in the Decal menu should keep you on the page of the selected decal.

Currently, if you have 3 pages of decals for example, selecting one of them on the 3rd page will automatically take you back to the first page. This is pretty bad, especially if you've organized the decals in a logical fashion where you might want to use decals that are placed next to each other. This is going to be more important as roll-and-write and roll-and-draw games become more popular
