Excellent Rated 5 out of 5 stars
After played with it for 5 minutes I disabled my Gmail Notifier.
Just one thing: it's a little complicated to open Gmail by this extension, you'll have to right-click on status bar icon, choose the menu named by your account name xxx, then choose 'open xxx' to open Gmail. Would you please bring us a 'double/middle click status bar icon' to do this? In any way you have a spare mouse button, left click or middle click.
