Rated 2 out of 5 stars

I'm going to play with it some more, but my main complaint at this point is that it won't allow mail to be opened in a new window.
Before filing a bug report, I looked at the FAQs and found this statement:

"open message in a new window doesn't work, and I don't plan on implementing it."

No reason why, just "I'm not gonna do it".

Maybe there's a valid reason as to why he won't be doing it, like it's difficult to implement, or he just thinks it's a bad idea. I prefer my emails to open in a new window. I don't like the tabs for several reasons, which is why I have it set to open in a new window. I don't know if the benefits outweigh this detriment. We'll see.


UPDATED: (I've disabled it)
While there are a lot of things in this that I really like, the inability to open emails into a new window is a deal-breaker for me. If that's not a deal-breaker for you, install this app, you'll probably like it.

I'll keep an eye on it to see if the author changes his mind though.

This review is for a previous version of the add-on (2.1.1).
