It would be great if we could right click on the raid battle button and open in a new tab, it is awkard going through each one one at a time to check how much you have done or the raid partys health especially when you have joined loads
I used to like being able to quickly jump in to each raid I was in to make sure each one was fully healed. It's a much slower process now so while I still do it, I do it less than I used to. Not sure how easy a fix it would be, you can't open any boss in a new tab, so presumably if it was done it would apply to all bosses. If it can be done, would help a lot.
My thought is that when we have a raid boss open, the "Bosses" and "Raids" clickables still remain visible, as if we're still in the general "Bosses" page.
if you want multiple tabs open, open multiple tabs for the game itself and then view a different boss in each one. problem solved!
