Running around mining I keep picking up thousands and thousands of fine sand and dirt blocks. When first landing on a planet I'd love a few slots where I can put the one of each block I don't want to pick up. A filter of sorts.
or a hot key to hold and click blocks to trash... or place unwanted block in"recycle bin"( 2-3 other trash cans) that only deleting items when overlapping tiles in it, but when place a tile, it will always keep that tile, but when count reaches 1000, it will automatically dump 500 of that particular item... ensure that players can keep 3 things on "always dump mode"... plus... players can still regret and "recycle" items by picking them up... it's more like "amount limiter", than "filtered trash" so instead having one tiny block for trash, we have one trash can and 3 recycle bin...
