Is it possible for a app similar to this but supports other email accounts (i.e. from MS Exchange)?

I really like the idea of the panel!

This review is for a previous version of the add-on (1.0.4.1-signed). 

The panel only shows the "real" webpage.
So, in the way I have developed it, I'm afraid no...

When the using the "compose" button from the contextual menu. Gmail reloads.

Should it do that? As gmail has already loaded and doesn't actually reload when I press the normal compose button.

Otherwise, I don't see any negatives.

First of all, thanks for the review!
About that "reload", is a side effect of the way I've developed the add-on. I don't use any API, so I must load a new webpage (url) to open the compose window.

Great

Improvements:
- Remove Ads
or
- Somehow allow other adblockers to be used (i.e. gmelius)
