Just spent an incredibly long time trying to find him due to the flashiness at my lvl 2106 made it all but impossible to see anything.
Chest arrows also really need another color as their golden color seriously bleeds together with coinspam from gold fever.
Perhaps give the merchant the same marker arrow, green maybe for friendly?
Also, the values of VERY high gold fever scores grows to take up ridiculous amounts of screenspace. Dont need to be that big. See the image and consider that goldfarmers sees that constantly, obscuring the screen even more.
