I'm pleased to say that after some very hard work in the past few weeks, version 2.0 of the plugin is now available for beta testing.
You can download the beta from here:
The new version has a totally revamped codebase, I focused on the plugin's architecture, and it is now using custom post types for storing the feed sources and imported feeds. For those of you who have a lot of sources, you should see a good leap in performance when rendering the page with your imported feeds.
If you are upgrading from a previous version, version 2.0 should retain your sources, please let me know if this doesn't happen.
There is now a new option to limit the number of feeds displayed, and I've removed the previous organisation of 'Today', 'Yesterday', etc.
Let me know if you encounter any problems!
