One thing I admired about Minecraft was the ability to use your mouse to transfer items in different ways. E.g. Splitting items equally over the tiles you dragged the cursor over, or just one on right click. It was very considerate to the user.
Here are some things I’d maybe like:
It could be taken further to automatically place items near items they are more related to. e.g. Don’t automatically place stone near your bread, place it near other stone if you have any. If you don’t have any stone, then place it near other construction materials, and so on.
In RPG style games where items take up multiple spaces and you have to have to play tetris with your items, I think some system of automatically rearranging loot items to reduce wasted space could be convenient. Perhaps only do this to items that the user hasn’t manually moved since picking it up, or provide a separate inventory for loot and regular items.
If there will be multiple interfaces on the screen, please let me drag items between them, not only between cotainers on the same interface.
In general, I prefer to use my cursor to move things, meaning move the item with the cursor until I click again, or let go, etc. It gives me time to think about space while I’m dragging the item and the cursor becomes a good visual for my mind. A key + click is then good for automatically moving an item.
