I would like to request that the graphics be updated to support high DPI Retina Displays on the new MacBook Pro's. This is most important for the status icon in the menu bar, as this is always visible. Currently this icon, and all other graphics, come out quite pixellated. It is extremely easy to add support for high DPI displays, and it makes the app look significantly better.
I would also like to request that the app be updated to make use of the built in Notification Centre in OSX 10.8. The current notifications look quite ugly, and are quite a nuisance. Utilising the built in notification centre would be a vast improvement.
It would also be nice to add the animated status bar icon like the windows version, to show when the program is scanning/active.
Of course these requests are both specific to avast! for Mac.
Thanks.
