Just a suggestion for the sprite gizmo and for the sprite collection anchor position...
I use bigger images for my sprites as I now they will be trimmed later when composing the atlas, but then, the gizmo/handle for that sprite is way bigger than the sprite itself.
Both handle and anchoring seems to use the bounds of the original image as size, not the trimmed bounds as the size of the sprite (or the mesh bounds if you preffer). I dont say this should be that way always (I use the anchor position on my benefit sometime), but a option for gizmos or anchoring (like when "upper center") using the sprite final bounds if trimmed, would be great.
Thanks!!
