I tried this new tool and I have few suggestions:
1. Since the gump is HUGE, put some alpha on the background so we can see a bit through it.
2. If you really can't put a button to edit the current criterias, at least put an X buton near each criteria to remove it without having to clear the whole thing when you have to edit a single value....
3. 1k to teleport, seriously? I could understand it if when you recall you're going exactly over the vendor with the inventory open and the item highlighted, but you get under the house sign and the luna houses are filled with dozens of vendors that looks all the same... So you have to pay 1k to go near the house, then you have to search the vendor when they are all equals (and often with the same name), and then search for the item that could be anywhere? Remember that some vendors are filled with rings that looks all the same, so you can get nuts searching for the one you have found before (always if the items stills there, since someone else could have bought it and you're going to waste your time).
Listen to me, just make the map to work as a recall rune for the house and forget the 1k thing
OR color the map with a random hue then color the vendor AND the item inside the vendor with the same hue (just for the player and just until you have the map) so when you recall you can recognize vendor and item immediately without too efforts. And in this case you can justify the 1k cost.
4. Put a small window (like the square that shows the item in the results) as a reminder of what item you have chosen (able to shows the item properties on mouse over) with the green border if stills available and red if not (someone bought the item/the vendor owner has removed the item). The window should disappear with the map.
You could also make this small window clickable so when you are near the vendor, it will automatically open all the parents containers and shows the item without having to search for it manually.
5. Add another context button: Locate the vendor. So when you are near the tracking arrow will point to the right one. Obviously it has to work only if you are near the vendor
