The blizzard tab prevents us from effectively doing undercutting and changing the default duration.

Possible features:

• Setting sell presets for a given item/category
• Display of items in bags (and amount of) that can be as a list in the tab - so opening the bags isn't needed; with one click on the item bringing up the selling options.
• Radio buttons to select duration (and changing the default duration)
• Showing list of other prices after posting an item
