Loving the new 1.6 version.
One thing I would love implemented is a better inventory management system. I have a suggestion, so here goes:
Stack identical items together. You have two rocks that weigh the same and have the same durability? Merge them into a stack. When one of those items loses durability, cut it from the stack. But instead of sending it to the bottom of your inventory screen, merge it in next to the already existing stack of rocks, to the right of those, and it just pushes the next item further down your page. This works well for remarkable items too. Maybe move remarkable items to the left of an existing stack of that item?
