@Puffy Hey Puffy, I looked at the script and it's not a lot of work to do this really, and, in fact, it would make the check for the shovel a lot less processor intensive (not that it matters on this kind of scale - you just mentioned it being "better" script wise so I assumed you meant efficiency?)
Currently, it searches every item in the players inventory, if it finds a bag, it checks it's contents for the shovel too, that's a whole lotta looping through items when you could just check at worst, the two hand inventory slots.
I am aware I just volunteered to do this though...
It's not at the top of my list, but, as it's a pretty small script change, I might get it done when working on something else, possibly.
Don't hold your breath
