If I understand your thinking, I think not, there should be no limit to the number of feed management. Indeed, the interface is missing a button "Add new profile", or something like that.When I see the number of feeds used by you, does it makes sense to think again more about the maximum number of profiles, which can be handled by WorldNews?
And now, the first feature request (easy) it would be possible to limit the news of each feed by date rather than by number?
Now there is only the "Count", but I'd use / add the "1 day, 2 days, 3 days" to (for example) a week.
Feature request Two (difficult): ability to hide the news once read. Operation: I hit send on the news, I open the browser, when I go out the news from the browser disappears from the list. If implemented, provide item on the menu options to display all the news, even those already read.
I hope I have not asked too complicated options. Anyway, thanks for all the work you're doing.
