As an additional irritation:
On attempting to buy things:
1. If I select a rarity and/or set a level range I expect it to remember that between the different buyer sections (armor, weapons, etc.). Currently it resets every time you change sections.
2. Having the filter window as a pop-down is really annoying, I would much rather have it as a collapsible section like the delivery box. Have it collapse to the search box, and then instead of a gear have it expand out to a full on filter.
3. There’s quite a few wasted pixels between the different filter options, you don’t need a <hr/> between each filter option, if you eliminated those then the filter dropdown (or hopefully collapsible window eventually) will be significantly smaller.
4. The pop-down does not go away when I change section (i.e. go from Armor to Weapons), even though all of the filter options reset.
5. The sell window should show the result of the subtraction of the listing fee and the exchange fee to give me the total profit. This can be a small coinage display below the total price section.
6. The My Transactions window shows the price I sold it for. Not the amount I actually GOT (afaict). This needs to either have an additional column that’s listing/exchange fees, or an additional column that tells me the actual profits.
