The Merchant (junk seller button) and Visualizer (junk item management) modules of Scrap are skinned to match ElvUI's theme.
Obviously both ElvUI and Scrap are needed, this is just an appearance modification :)
v1.0 has been tested with ElvUI 5.99 and Scrap 12.4 for WoW 5.2.0
Installation / Usage
Just extract to your addons folder, nothing further needed.
