I want to be able to have the option to sort my lists by Tags, so that you see all the items on the list, but each ordered by it's tags, if present (if the item has no tags then it would still appear on the list too). This would be good, because then you can use the tag feature to create sub-lists in a sense, but one's that are compatible with integrating with Outlook and other external software.
Just realized this topic is 4 years old :-(
It's just an obvious thing to have - it makes even sense for Contexts
I'd love to focus on a context or tab, but not have other things invisible!
