I downloaded fishbown a few hours ago and I can only say thank you and congratulations for making this really really useful program.
I have only seen 1 issue and two suggestions.
I've already posted the issue in the tracker, and the suggestions are to locate the program and to do a new posts count in the left's menu (like google reader) or when the program autoupdates the FB infos to be highlighted differently to know what news are
newand what old.
I don't know if it's possible but it will be amazing if Fishbowl do that.
Congrats and Thanks for the app.
PS: Sorry if you don't understand something, but I'm spanish and I tried to explain the idea the best I know.
