Well i wanted to check if you could open mutltiple worlds in one graal tab, but after looking there wasnt anything to be found. instead i had to open up another graal window yet again, and if to many are open the icon tray happens to overflow.
if you could load such as 2 or any amount of more worlds in one window, then im sure that wouldnt be a problem. I know it might not be something to worry about but now you cant even open up 2 worlds if you have lots of things to do on other places at once. It detects it as supposed account sharing, well i think thats what it said to me.
Anyway, I dont know if it would slow down the graal client then forget it but if it would work just fine then like you could put the other world on the tab at the bottom.
