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.
Things that are broken right now (so I could get a working version for 9.0.1):
Emotes and yells aren't picked up yet.
Nameplate scanning.
Cursor mouseover scanning.
Things are working:
Menu system and alert system redesigned with 9.0.1 changes. The old version will pop up with Lua Errors once 9.0.1 hits.
Removed the icons for alerts and only give names now since Blizzard sometimes calls objects as creatures and creatures as objects.
Expansion and Zone alerts per Zone using a new menu system. Type "/DRS" to open the options window.
Vignette scanning. These are the star for rares and the chests for treasures on the minimap. This doesn't work completely for WoD, but should be working for Legion+ zones.
Basic support for Shadowlands zones using vignette scanning. I've tested it enough to know a rares and treasures are popping up.
