Everything I could find around this issue pointed towards it being a bug in the Windows Phone storage management, rather than in RSS Central. Have any of the recent WP updates (GDR2 and GDR3) made this better for people?AdminAdam Dawes (Admin, RSS Central) commented
I've yet to discover exactly where the space is going. The next release of RSS Central will have some additional debugging code present that will hopefully help me to track this down.

Both the Windows 8 and Windows Phone versions of RSSC already have options to view feeds by category. In Win8 it will filter the subscriptions list by category, in WP it will additionally allow you to see all articles within the category. Do either of those satisfy your request? If not, can you let me have a little more detail as to the type of thing you're requesting?
