-Teleport (cuz you rather remember the place's name instead of which sub-section that place is located in)

-Achievement (let's be real: finding specific achievements from a long list is painful)

-Challenge Log (less scrolling)

-NPC Trader's item list (so I can find Rock Salt without scrolling half of the section full of cooking ingredients. Or some specific dye)

-Blue Mage spellbook (It has a filter function, yeah. But would be still helpful to have a search function)
-Triple Triad card list (same as above)

-etc.
