Great idea Rated 3 out of 5 stars

I just install this addon.
I enjoy the idea, nevertheless, I confirm Nick2222's review concerning compact header (the header pane simply disappear when both extensions are active).
The error console shows an error at line 279 (this.expectReplyCheckbox is null).

This review is for a previous version of the add-on (0.1). 

Thank you for your review. After I read Nick2222's review I tried installing Compact Header 2.0.6 and I didn't experience that problem. I need more information in order to reproduce the error and to resolve it. May I know the version of Compact Header you are using and whether there are any other errors? Thank you very much.
