This is indeed a very good idea, would be great when opening a gmail account from thunderbird to have the option to open the account directly from www.gmail.com, and somehow keep the sessions separate, i mean if i check another gmail account from TB and click the "Gmail Tab", to have two separate sessions and be logged in both gmail accounts from www.gmail.com. I hope is understandable.
Keep up the good work.
