Looking for Feedback on Thunderbird Integration

I started a little project to integrate Nozbe with Thunderbird, and am looking for some feedback on features and users to test the initial release.

My chief design goal was to keep things real simple. I did not set out to build another Nozbe client in Thunderbird; rather, I was looking for a way to get the contents of e-mail threads into Nozbe without copying, pasting or forwarding with edits the way it’s done today. The add-on implementation is very simple — a cascading popup menu is available for any mail item/thread in Thunderbird, and looks like this:

I am looking for feedback on the following possible features:

1. Add e-mail attachments as files (no API for this yet, but demand will help)
2. Separate Inbox from project list — this can be implemented as a separate “Add to Nozbe” menu that will add the e-mail content to the Inbox project. The Inbox project will not be included then in the list that shows under “Add to Nozbe As” menus.
3. Add to Nozbe in Context menus — item goes to Inbox but allows you to tag it with a specific context (I know Nozbe 2.0 will allow multiple context, but right now only one is supported)

Any feedback is appreciated.
