Mouse-overlap

Pop-up layers is a simple and elegant solution, but, if employed site-wide, produces an unweildly layer list.
Early versions of Photoshop suffered the same problem until Adobe introduced a layer tree where related layers could be nested/grouped into sub-folders.
Perhaps Xara could consider adopting a similar layer tree in later versions of XWD?

A very attractive interactive map by the way.
