In the current state, when I open a feed with a lot of elements while in focus view, it will try to show me items matching to the intelligence trainer. That’s good.
However, this is happening even for feeds for which I have no “focus” rules, which leads to a long “refresh blinking period” in the story list, until it went through all available items. It seems like this could be directly checked, to avoid unnecessary work.
Typical example: I’m on the home view (focus mode), and I click to try the recommended site (zenhabits, currently, which has a quite long RSS). I obviously have no rules for it, since I don’t even have it added. However, it will still spend a long time loading, to find items to display.
