I would still prefer GMail Notifier

Well, I would say, its an enhaced form of GMAIL NOTIFIER, a small application which sits on your menu bar and which is lighter on your computer resources, quiter, more stable and having a smaller window. But again, in Gmail Notifier you have to open the browser when you need to read your email or reply/forward/send them but in this app you can do everything from its own window.

I have also found a bug in Mailtab for GMAIL. Whenever I try to reply an email from its own window, my computer switches from integrated graphics to discrete graphics, which is an indication that this app requires a heavier graphics card. Even when I am not doing anything after replying an e-mail, my computer stays on discrete graphics, making itself hotter and draining my battery till I completely shut down this app from the menu bar.

I am afraid I am gonna stay with GMail Notifier because I think its a much better application which doesnt demand your attention all the time.
