For example, I have 3 tags for location: Home, Office, Outdoor.
And I have another 3 tags for time: Focus Time, Leisure Time, Fragmentary Time.
Then there will be total 9 (3*3) combinations of location and time. Shall I create 9 perspectives for them?
I think there should be a quick filter with multiple tags, I just need to select several tags, and the actions with those tags will show up. Also need url scheme for this, such as omnifocus:///tags/Home,Focus%20Time
