Suggestion - add a "sort" option to the inventory. The categories are great, but it'd be nice to be able to sort within those. It'd be much nicer if daggers were followed by all the daggers with varying amounts of +speed/damage so I don't have to look through a giant list for them.
Additionally, it'd be nice if the items with a modifier have that modifier in the name. So "Dagger (+Speed)" or "Dagger (+3 Speed)" or something.
