One more time, I was replying to the comments made by the seniors. Although, there were few comments, there were some additional features in the release. I have moved the Attachment Keyword Box in "Composition Tab" in Options. To make these move possible, I have to create 3 new files and some additional code to manage those files. In the end, it was a happy day when I submitted the patch with all those issues covered.

Nothing special in the release 0.5. I have been fixing all white-spaces issues, all indentation issues and some other issues. I also had to get 2 clean boilerplate licenses for my files. It wasn't an issues. I was feeling really cool that I am the first one to get a clean license in 2009(I think so because I took the license in the first week of the January, 2009). By the way, I have uploaded the patch for my 5th release on the [bugzilla.mozilla.org/show_bug.cgi?id=244455[bug]]. Feel free to visit it and try my patch.
