Suggestion #3556

The current crate system puts in keys in the inventory of users if they buy them / get them on voting. After that, they have to go to /warp crates and open the keys. Sometimes, the inventories of the users are full and they waste money on keys. This system is not reliable. Instead, a /crates command should be added which opens a GUI that shows us different keys and how many keys we have with us. This would be a really good feature and I highly recommend adding this. If you don't understand what I mean, I'll be glad to show you screenshots of what I mean.
I hope you put my suggestion into consideration.
