To begin, I am no coder. I am looking for an add-on that will allow me to change the actual color of the folders under my Inbox and have any emails associated with that folder match the folders color REGARDLESS of how it arrives in my email. Meaning no redirects or manual moves, maybe have it look at the senders email and/or subject line.
And one really big wish is that it keeps working on all future releases of ThunderBird or have TB ask before updating because it will break my add-ons. Even better is if TB actually codes this feature into the main platform so it becomes standard.
Thank you for your time.
