Hello everyone,
Sorry for this late answer to all of your questions, but we've been quite busy with the epub output and the API. Now that our API is open to anyone, it should be very easy for anyone with decent programming skill to create software using Feedbooks:

About the news section: we need to support cache on the RSS feeds in order to output epub files. This means that for the upcoming weeks, we'll focus on both cache and epub for the RSS/newspapers.
Flamaest: You've got some pretty good ideas here. Displaying the list of RSS feeds in the newspaper edit screen for example.
I'd like to create some sort of "fork" system too. If you discover a newspaper that you really like but that need some extra editing to suit your taste, you could basically create a newspaper using this one as a template. Much easier than having to add manually all the RSS feeds.
For the libprs500 output on our sync tool: we can make this work, but auto-sync won't work. This mean that instead of simply plugging your Sony PRS-500, you'll also need to press sync on the tool.
Is anyone using our sync tool with the PRS-505 ? I know that the 505 can automatically sync with a local folder. Should be very easy to sync and read multiple RSS feeds with the 505 everyday.
