When you apply a filter to a feed, you want it to persist. You don’t
want to reset it each time you visit the feed. Group and profile feeds—and almost any other
feed where you select a feed filter—now hold on to your filter. The filter for that particular
feed stays in place, even when you close your browser or navigate away from the feed.
This feature is available in Lightning Experience.
Stickiness applies only to the feed where you set it, so you can set different filters on
different feeds. Clearing your browser cache clears the filter, so the next time you visit the
feed, you get the default filter.
Sorting options and filters on the What I Follow feed aren’t sticky.
