Allow categorising labels and selecting labels using the categories

[agrogers]

I listened to your video about using labels as a way to create sermon notes. I liked this idea but then i realised that these sermon notes labels will appear in my label list. I never really want to see them except in Workspaces that I choose or perhaps on other rare occasions. So:

• being able to categorise labels could be good. Labels might include 'Sermon Notes', 'Bookmarks', 'Labels', 'Faith vs Works', etc
• It seems that i might want to keep bookmarks (the main highlight colors) separate to miscellaneous secondary labels. Hence 'Bookmark' and 'Labels' categories.
• this would allow me to easily view just the label group i want (if we had a select All and select None) button at the bottom of the screen.
• Workspaces could be tied to the categories rather than a selection of labels. I think that would be good for sermon notes.

Not sure how useful this would be.... but it feels like a long list needs some management tools.
