Reorganise the skilling outfit tab of Diango’s Item Retrieval to mimic the Armour tab of the PoH wardrobe: outfits are displayed under just one of the 5-piece outfit’s item icons (with the other pieces visible either through a hover-over description or only after left-clicking the outfit icon) and can be withdrawn/stored with a simple right-click.
Another possibility: enable a right-click option upon the skill itself to withdraw skilling outfits (right clicking “Hunter” after unlocking the volcanic hunter outfit will reveal a “withdraw volcanic hunter outfit” option, for example).
