Not a UI expert, just a user’s two cents. Trying to find, move, organize files and folders in Google Drive could be much better. As is, the current UI detracts from an otherwise great real-time collaborative tool.

As that forum page shows, Google Drive changed it’s “Add to my Drive” to “Add a shortcut to Drive”. This makes sense sometimes, but in some cases, especially if you use “Backup and Sync” you want “Add to my Drive”, otherwise you can’t sync the document/folder. The way to use “Add to my Drive” still is Shift+Z. This switch was never mentioned to me as a user, and the solution was not obvious.
