Cool add-on! Now I can get the last update without checking the site periodically. Placed where it should be, at least in my opinion. Not intrusive. Require low resource, I think. Just one big picture and the rest are just texts.
Pop up will be nice but then again it could be intrusive. :D
I miss the settings. :( Do I get a chance to choose what I want to be updated with? Occasional suggestions of what's hot would be welcomed, though.
Overall, it's just cool. Awaiting for the next version. :D
