Suggestion - autodelete slots for "infinite" items.
Since our inventory slots don't take all available space in the interface, there could be a row on the bottom with slots colored red for example allowing us to put items that go to trash automatically.
Items we could place there would be only let's say ingots, belts, ores... name it. Only these easily reproductible. You wouldn't be allowed to put here slugs, shards or anything made in workshop.
The reason for autodelete is to get rid of tedious mass item deletion from inventory after rebuilding base for example or during cleaning areas of foliage. Since we don't have any QOL shortcuts like "shift+ctrl+click" that would delete item, we have to drag and drop into trash every stack. Boring and tedious.
You can even add numbers to these slots, meaning to delete stack only if there would be more than provided number of stacks in player's inventory. So if we put "4" in the slot and put screws into it, we go with 4 stacks of screws in inventory and anything more than that gets deleted automatically.
Something like this:
