Just download 5.0 for Mac. Looks good. It would be helpful to not only see a list of all tags, but to also be able to view all tags that occur in any one notebook/subject area only. For example, I have a multitude of notebooks related to work and personal. One of my work notebooks has many many tags (I like to think of them as files). Many of the others have only 1-2 tags. When I see a list of ALL tags for ALL notebooks, in alphabetical order, I still have to look for particular tags for any notebook I want to view. Is it possible to have a drill-down from ALL TAGS -> ALL TAGS CONTAINED IN _________ NOTEBOOK? Or, when bringing up a Notebook, to see a list of all the tags in that notebook? Thank you.
