Code review comment for lp:~rpadovani/reminders-app/tagsUI

- What's the criteria for ordering the tags list in the new tag dialog? Most used first?
- Would it be possible to show those which are selected at the top of the list? This would give the user feedback on which one they've just added (so that they don't have to scroll down the list to confirm). Also it would make removing tags easier, so that, again, the user doesn't have to scroll down the list to find the selected tags.
