Add conditions to the "hide feeds" feature


"Hide all read feeds" is very convenient. Sometimes, I would like to parameter this even further. For example (xx is a number that can be changed)
- "Hide feeds with less than xx unread articles"
- "Hide feeds with more than xx unread articles"

Display unread feeds with less than 10 articles.

Hello,

I would really fancy this feature. For example, I want to display only unread feeds with less than 10 unread articles in them. It helps increase productivity in using feedreader.
