Alright, I think I've reached the final equipment selection layout! It's a lot more simpler and friendly. Instead of an overwhelming list of items, there are two drop-down for the main/mount, as well as a list of modifiers. The stats are simplified to just those on right column. The window is a lot smaller as a result! Note the UI for the item count. Also note "Light Pew Pew Cannon"? It's a result of me implementing "description" that allows you to put the main item's name within the mount's description.
What do you guys think?
