I recently installed this reader and I like it. The only feature that I would like to see is a configurable refresh (say, 1 to 120 minutes). Maybe the toolbar icon could flash to show the number has changed recently.

You could define the automatic refresh delay from the option tab in the update menu.

To flash the unread number you could use a pinned tab with the "Tab badge" Firefox add-on.
