Suggestion: /crate remove (With single crate set) should just remove it, not require a name.
99.9% of the time people will be using 1 crate on 1 block.
/crate remove should just remove the crate on the block and not require name input if there is only 1 crate set, and if there are more than 1 crate, it should LIST which crates are set on that block in chat and allow clicking them in chat to remove. Otherwise you need to figure out what the crate name is, then type it, this could be simplified.
Same with /crate set it should open the crate list and you can click the one you want to set it to (even better if it opens a GUI with all crates instead of chat) as chat moves fast.
Currently, we have tab completion to show which block has a crate and what is settable. I like these ideas and will be interested into implementing these in the future.
