I'm always doing quests and I hate how I have to go "back to quests" and then go from there. Why not have a Next button or Continue button. Same thing? It may not be a big difference or matter to some but it could save a few seconds in questing also.

Am I the only who thinks this is a decent idea?

Eh. Often I'll middle/triple click on "Start Quest" so it opens in a new tab. I open the shop searches for the items in new tabs. I control+w to close the tabs I'm done with, including the active quest once it's turned in. Rinse, repeat.

That said, this is still a good idea for mobile-friendliness.

I didn't even know you could ctrl+w to close the current tab. You just made my life even easier :P
