I use HKN so I'm not familiar with ISB. I keep 1 screen open and minimize the other 4. I see the merit in your advice, but idk how that would work for me. Also seems to me there are alot of addons out there that show countdowns on bars but the screen clutter is too much for me, and I havent found one that shows my alts cooldowns.

I use ElvUI in healer mode as I like where it shows my party. I use Jamba as well. Is there a plugin for either of those?
