Rated 4 out of 5 stars

Works very well, but is in conflict with "Minimize to tray Plus" for Windows (my version is XP).
Is it possible, as outlook (yes, it's bad, I know :) ), to indicate it in the tray ?
I had disabled Minimize to tray to make your beautiful option functional

This review is for a previous version of the add-on (1.1.5). 

Thank you for your appreciation. Concerning the tray icon, I will consider that, but I fear I would have to redesign too much this extension code for implementing it...[September 3, 2010 UPDATE]: I tried to add a sort of compatibility with 'MinimizeToTray' addon in New Mail Attention 1.1.9: my addon should restore TB from the tray before alerting the user. It works perfectly on Linux (of course that's my opinion...), but I think the behavior under Windows (I tried it with 7even) may be a little annoying (it may be worth giving it a try anyway).Please let me know if it may fit for you: if you don't like its behavior, you may turn it off by unchecking the menu entry 'Tools --> New Mail Attention --> Restore from tray' (this entry is displayed only if MinimizeToTray addon is installed and enabled).At the moment version 1.1.9 is still awaiting for review by AMO editors but you can download it from this link: https://addons.mozilla.org/en-US/seamonkey/addon/191033/versions/
