It would be great if we could apply a tag, or rename a file or folder to something private to the user rather than what the original owner named the file.
Today we can move those items into Collections to manage them with our own naming, but that doesn't resolve the issue of individual files or folders with ambiguous names.

For example: I need to track certain files that a bunch of different teams are working on as part of "Company Project 1". I don't need to see everything the teams are doing, so they don't grant me access to their entire folder structure. Instead they just give me access to their "Project 1" folder.

So now, I have 27 different "Project 1" folders for each of the different teams, and there's no good way to know which one I'm looking for. I could create 27 different collections each with 1 folder... but that's cumbersome and not really helpful to sprawl.

What I'd much rather have would be a personal "Project 1" collection with 27 folders named for each of the teams. They don't need to see the folder names I use -- it would be a unique name/tag/view just for me.

Today I do this with a personal folder full of bookmarks... but the overall sprawl is still there behind the scenes (and especially when searching, the bookmarks do nothing to help.)
