Reports rares and chests found in zones with Vignettes (the star and chests in the minimap since WoD). It pops up with arrows and distance markers pointing in the direction of the rare or chest.
Type "/DRS" to open the options window.
New command: "/DRS ID" - Use this to print some information out to chat and report it back to the author to get something added to the list of denied vignettes.
Long-term I'm going to rewrite the options and menu system to allow for some cooler things.
