ItemFavorites is a small mod that enables you to... favorite items! Marking an item as a favorite can be done by holding the 'ALT' key while clicking on an item—doing so consequently:

• Surpresses vanilla item interactions including:
  • Dropping favorite items both in the hotbar and from within the inventory.
  • Quick-moving (i.e. shift clicking) favorite items to other containers.
  • Swapping (i.e. number keys) favorite items with another item outside the inventory.
• Surpresses item transfer mechanics for a few mods including:
  • Preventing favorite items from being quick stacked when using QuickStack.
  • Preventing favorite items from being sorted when using Inventory Sorting.
