Allow the use of tags across notebooks and users. If my partner creates a new entry in one of her shared notebooks with a given tag, and if I use the very same tag on a couple of entries in my own shared notebooks, we end up with two separate tags with the same name. Currently, I can not see all the entries with this tag, I must either select the first identical tag to see part of the notes, and then select the other identical tag to see the other part of the notes. If I select both tags, I see nothing, as although they have the same tag, it is considered as different by Evernote. To me, this is a bug.
