Title
Filter out community entries by flist or custom fgroup membership

Short, concise description of the idea
Offer a way to view your friends page, or community journals, that restrict displayed entries to those posted by someone you friended, or in a specific custom friends group.

Full description of the idea
At times, the volume of entries posted to some communities can be overwhelming, and it would be nice to be able to filter entries down to those posted by people in a list. For ease of maintenance and to avoid having another user interface, that list could be people you friended, or people in a custom friends group. (In both cases, that would be a per-community option, perhaps with a default setting.)
An ordered list of benefits

• Another way of pruning entries in high-volume communities to a manageable volume without taking it off your fpage completely
• A way to track community entries by interesting people (for whatever definition of "interesting" works for you) more easily

An ordered list of problems/issues involved

• Uses severely limited (for now) developer time
