First off, there are probably many people that have already asked for this in one form or fashion. I did see one comment regarding this in a PTS discussion but no real answer that I saw. With the game being built around Crafting and Crafting built around Researching. For those people trying find specific items but not necessarily one specific item regarding researching items, I would like to suggest three possible ways to help those individuals searching guild traders.
1. Modify the Filters to allow only searching for items that the current user reviewing the Guild trader can research. The program is already showing researchable items in the right Description pane, but you would have to scroll thru 100's to find the ones you wanted.. Maybe introduce a simple toggle to say "Research Items" Yes or No (where No by default would be everything)…
Or
2. Allow the Trait filter to allow multiple selections so that you do not have to cycle traits one at a time for each guild trader you are visiting.. Very time consuming one at a time..
or
3. Allow the name search to have a way to search multiple terms maybe separated by colons or semi-colons or something. If this already exists, then I am obviously not using correctly and I apologize in advance..
