There are number of gmail checker plugins for different browsers. Chrome also has couple of them. But here is an extension for gmail, that does some pretty smart stuff.
Gmail Checker Plus, has some cool features.
– 10 different icon sets, choose your favorite!
– Mail preview window
– Delete, archive, spam, star and mark as read functionality
– Google Apps support
– Mailto-links open in your Gmail or Google Apps Mail account
– Monitor all your labels
The mail preview window is myÂ favoriteÂ feature. If you look at the picture here, you will get a good idea about how this works. Instead of just viewing the number of unread emails on your inbox, this window actually helps you reply, mark read or mark that email spam.
You can select how the plugin windows should look like. Change colors of the icons depending up on your taste. See them in action in the image below.
Now, go ahead and install this extension and play with it ! Install it from here … and dont forget to leave your feedback in comments !
