Which UI should MapleStory use? i did a poll

However, now you can use tab to switch tabs in the inventory menu which you couldn't do if you used to open all windows up at once (because having more than one window with tabs makes the tab key do nothing because it can't choose which one you want to be tabbing through). Very very useful if you often use return scrolls or equip decent skills because if you're on a tab like cash shop or etc and you want to get to use or equip, you just have to hit tab once or twice instead of moving your mouse which is usually slower of an action.

That functionality doesn't do anything for me, personally. Never will use it.

But, having 1 key to open my pertinent windows was massively useful since I could remove 3 other keys from my keyboard layout.
