Possibility to create tags not associated with notes

I've reworked my use of tags. Now, I've detected a problem for me. I can't create a tag which isn't associated to an note. I will in the future assign all my new notes to a predefined list of tags. I think, this is a good way to organize my notes and tags, so that these will be well arranged for use. So, the possibility to add not associated tags will be very desirable.
