Gaze is a lightweight Gmail checker that sits in the system tray and notifies you of new messages in your inbox. You can configure how often the program will use the ROME API to check the Atom RSS feed for your inbox, as well as optional combined notifications, custom browser actions, theming, and more.
Great program worth the effort
Although it is 3am and I've been working steadily for the last 5 hours (half of which was jerking around with Cedega), I eventually got Diablo 2, it's expansion, the latest patch, and Battle.net support, all running, all under the latest build of Wine (using the prebuilt Slackware package, an optimized compile comes later :) ).
Great to see the effort being put into Wine, it's a really useful piece of software and was fun to learn about (especially with the extensive documentation). If you dual boot, try migrating over some Windows apps, I know I'll be booting into my Windows install about 90% less now.
Keep up the good work!
