When working with many layouts, it becomes necessary to organize them in folders (and subfolders). But placing a layout in a folder actually hides it. Attempting to locate it in a hierarchy of folders and subfolders quickly becomes quite frustrating as one has to mouse over pretty much every folder. When a solution has 200+ layouts, this minor omission turns into a constantly frustrating issue.
Why not give it the blue background color show that the used layout is within that folder and then blue background color on the layout that we are on.
