With the release of the new Thunderbird Nightly, supporting Extensions. I decided to take up one of the ideas for extensions.
I want to create an extension that allows users to easily customize and add colors to each level of quoting. I use this myself but not as an extension, so now I just gotta find out how extensions work… Which is not as easy as I expected

Not a bad idea at all. Unfortunately i’m no coder so I can’t help you there.
there is another extension that I have been looking for for some time now. I want to be able to archive old e-mails similar to the way it is done in Outlook.
Any ideas anyone???
