Hi Douglas and others potentially following this thread,

The compose in a tab experiment is and remains an experiment. I have no 
time to invest any more time into it, so please consider it as a dead 
project from now on. (There should be a disclaimer for that on the 
addon page on

The goal of that experiment was manifold:
- perform all the composition process with as much as javascript as 
possible: most of that work has been recycled for the Thunderbird 
Conversations addon and its quick reply feature (which is actively 
- experiment with another editor for writing html mail: the ckeditor 
has been a less than satisfactory one, and I don't think we want to 
keep it if we were to do future iterations of this thing,
- implement the compose in a tab feature: since tabs on top just 
recently landed on trunk, I'm pretty sure we'll see that fixed in the 
upcoming months.

Thanks for your interest! Cheers,
