## Why It's Good For The Game

There's been SS14 players moving to SS13 and finding dropping in 14 is
better, which I kinda agree as it allows you to be more precise with x/y
dropping.

## Changelog

🆑
qol: There's a keybind (default is Ctrl+X, rebindable) for the drop
hotkey to drop where your mouse is (similar to SS14).
