For someone who's sold most of his possessions to cover his debts, Gamlen's house is sure cluttered with a lot of chests and quest markers! This mod automatically moves all items from DLC item packs to personal storage (which has a much better interface for retrieving the items you actually want!) and deletes the empty chests (and quest markers) left behind. The quest entries in the journal are marked complete. Item codices are gained when you move the items from personal storage to your inventory. This cleanup happens in the Amell Estate as well.

I opted to leave the special deliveries chest alone, as the promo item codex spam and level up from XP gain was rather irritating completely out of the blue, and because it's a good location to deliver modded items.

This mod will also hide the giant statues (and quest markers) for Mark of the Assassin and Legacy DLCs -- in Gamlen's house in Act 1 only. The quest entries will still be in the journal, as I didn't want to risk messing with the plots. The statues will return in later acts in the Amell Estate. I never want to play those DLCs in Act 1 anyway so the quest icons just bother me. If you don't want this behavior, delete PRCSCR_sph_dlc_hide.GDA from the folder. You must do this before entering Gamlen's house with the mod installed.
