Feature Request
The new feature that would mean the most to me at this time is the ability to select an ID, and isolate all the posts by that ID.
Either temporarily disappear all the posts that aren't by that ID, or enable a new navigation tool similar to the existing Notables, Own, or You tool.
This would be extremely helpful when a "special ID" is dropping, to rapidly evaluate whether that ID is worth paying attention to and possibly capping their posts for further study.
Would it be really easy to implement, say by just cloning already-existing methods?
