I agree that a stack of bookmarks has limited use, because the poor user has no idea of what boomark #5 actually is at a given time (a moving target).
That is why I display filename of a bookmark. Previously, the poor user has to face ice-cold bookmark 1/2/3/4/5.
BTW: Why don't we allow the user to label bookmarks? That would be a good compromise.
This is similar to my tag idea. But if it needs another dialog, it has to wait. Bo
