Can other people see objects from this MOD in multiplayer?:
If other players do not have the MOD loaded, they definitely will not be able to see the objects from the MOD.  Although all of the objects in the MOD are vanilla items, the Object ID's do not exist in several key files in vanilla.

If I remove the MOD, what happens?
The objects from the MOD will be removed from your save and go poof in-game, as the Object ID's will no longer exist in multiple key files. 

Why aren't there individual icon files for each object in the mod?
Although each object in the mod is vanilla, most do not have a vanilla icon, which would be useable by the mod.

To make icon files, you take a few screenshots in-game, go though and pick the best, in a decent graphic editor program, remove the background, clean it up, convert to DDS, 4x,BC7 compression, at 256x256 px size.  MINIMUM 30 minutes per icon.  Multiply times the ~900 items in the mod. 

If anyone would like to do this, feel free.  I'll give credit and implement.  :)

Until then, 13 decent vanilla ICONS, divided by subcategory, are used.
