It would spin your camera when you went afk. I have found one called XyAfkSpin but it seems to be out of date. A guildy of mine is using one but he can't see what it's called. Any helped appreciated. Been looking for one for a good 30 minutes and I'm about to give up :/
Did you actually try that addon before disregarding it? An addon being out of date doesn't always mean it's not working, try to install the addon and check the "Load out of date AddOns" option. The WoWInterface version of XyAfkSpin has more recent updates than the one on CurseForge, so make sure you use that one. If it doesn't work, you could try AFKCam, however its latest update is just as old as XyAfkSpin's latest update.
