I do not have permission quite yet but am already in a discussion with Gallahead about this but I am looking to continue ThinkTankUI as an ElvUI extension/edit. Here is a link to the album that I sent him and I am looking for feedback/future testers to give it a go to see if it runs smooth for them. Check it out and let me know your thoughts. (This is not a published UI and will only be published with permission of Gallahead, which seems quite likely, so just sit back and enjoy for now)
