I love using this add-on, it's absolutely one of the best add-ons for Cyrodiil. We get to know where the fight is, what's being attacked, not to mention there's a raid/group window. The add-on developer has stepped down and asked in esoui for someone to take over.
Please don't let this add-on be forgotten. I know there's a lot of pvpers out there that rely on this add-on. Please, someone with knowledge of add-on making, take over that project.
