A new version (v0.22 public alpha) of [b2] Gmail Notifier has been released! You can download it from http://b2labs.com , but the software will automatically offer the update option for you. This version contains a critical bug-fix - the huge memory appetite has been hopefully reduced please keep in mind that the application is still in ALPHA development state, so if you notice anything else, please don't hesitate to tell me - you can report a bug or suggest a feature easily any time using the app's "Report a bug..." menu item.
I've also added a few new animations, check out the animations section of the site.
Thank you for using the software, and helping me make it better!
