nice, but some display proposal Rated 4 out of 5 stars

great addon for me,
just some visual enhancement proposals:
would it be possible to have it started but not displayed in menu => alt+q would work?
another question, would it be possible to move it to the same row as "get new messages" and "create a new message" as well as search box is present?

any of these 2 would save me some space for e-mails displaying that is so important for me.

thanks

This review is for a previous version of the add-on (0.3.0). 

Cutomize toolbar ...

Thanks for the feedback !
To free room for mail visualisation, you can remove the QFM toolbar, and add it in an existing one by using the "View->Toolbars->Customize..." properties of TB.
Removing QFM from the Tools menu is not an option today, but I can consider it for a future release.
