Just as a quick reminder, my project was to add a functionality which reminds user to attach attachments in Thunderbird. To read more about it look up this Bug.
Till 0.2 release I have added the functionality to check in the body of the email. This check will remind user to attach attachments based on some keywordds. In that feature I had a few default keywords.
For 0.3 release, I needed to add a functionality which allows a user to Insert, Edit and Delete those keywords. And I am glad to announce that My code is working fine for "US English" Thunderbird.

Finally, I would like to thanks all my supporters. And hopefully, I will keep supporting open source community.
