It's less the amount of time I find annoying, but more the sheer number of clicks. Getting in and out of the retainer menus is clunky and not being able to even accept group invites while one is open is annoying. And trying to organize multiple retainers at once? An irritating hassle. I have three and it's driving me up the wall while I'm trying to clean out and organize my stuff right now. Would save a ton of time and frustration just being able to call them all at once and view their bags at the same time :/
