In this topic the issue was raised that when you are in the library and search, say, Cycling you get a bunch of filter options (including 4DP focus). It looks like this:
However, when you click on a Channel, say Sufferfest, first, the filters are incomplete and look like this:
It seems to me (and others on the previously mentioned thread) that when you click Search, you should always get the same filters. Perhaps if you start in Sufferfest, the Sufferfest button should be pre-clicked, but otherwise, it seems silly for the search filters to be dependent on where you start.
