Background/Rationale

Quick filters are very helpful.  We use them extensively to help slice&dice the backlog into different views for different purposes.  As we do this, though, the list of epics in the Epics panel remains the same.  

When I use a quick filter, I do so because I want to focus on something (or to help the product owner focus on something).  For example, one of the quick filters relates to a particular component.  Not all of the epics are relevant to that component.  This means that we are sorting through (i.e., distracted by) epics that aren't relevant.  It creates mental clutter, if you will.  

Similarly, it is difficult to assign issues to epics, because the epics are ordered by priority rather than component-proximity.  This requires much scrolling of the Epics panel, which adds friction.

Suggestion

It would be lovely if there were an option (maybe something akin to "Create epic"? instead of???) to apply a quick filters to both the individual issues in the backlog and the list in the Epics panel.
