BestInClass++ is a SKSE plugin for Skyrim Classic. It improves the BestInClass functionality offered by default in the game, by considering more categories and types for armor, weapons, and similar.
Update 1.1.0 fixes disappearing markers, and includes the player items in the Barter and Container menus. Internally the code has been restructured, cleaned, and now hooks the appropriate function instead of disabling it.
