Agreed. Andrew Gilleran raises a good point here. The new experience has introduced several "clunky" pieces of functionality...
Would it be possible to have the old profile dialog back when uploading but make it work for multiple uploads, with a tick box at the bottom saying "apply tags to all files"?
The market place has been resistant to metadata because of the network-share hangover. At it's core there in an reliance on saving to a "location" - a sub folder many levels deep.
While metedata is/was the perfect solution, adoption rates suffered as the entrenched dependancy on folders is a decades old habit that is hard to kick.
With the advent of teams/groups and this new experience Microsoft has given up fighting the uphill metadata battle and almost reverted to an environment free of metadata. While it's still there in the background Microsoft have all but obscured it with this clunky, google-drive information right hand pannel.
Navigation is another equally big can of worms with governance ramifications that go beyond the initail or even sencond thoughts one might have.
