actually, it would be even better if the shovel would switch to “saber mode” automatically, if it would had hit the enemy once the user clicked, though, it would be probably clunky and manually using it would be more preferable
Currently if you use melee hotkey or that fire button with shovel equipped it does the digging animation. So instead of digging it could do a melee swing. If you want to dig you just use the fire button.
