Hello people. I wrote a simple, small mod for PZ, called Priority Sort. It alters how the "Category" button in inventory panes behave. When you click this existing "Category" button, it'll now cycle between various categories, and push any item belonging to that category to the top of the list. Any other item will first be sorted by alphabetical category order, then by name order. Double sorting the inventory, but first prioritizing the selected category in other words. Neither overwrites any vanilla files nor affects your saves; only alters the UI to include a custom sort function. You can find this mod in the Steam Workshop as well. Screenshot - PrioritySort.zip Note: Some categories are disabled. The new "ammo" category for example, as the game still treats it like "item" category. Even without this mod, sorting by the alphabetical category order will not result in "ammo" category going to the top. The other disabled categories are disabled as they are very rare and/or redundant ones.
