Simple server cash is meant to be fair and actually worth something (I guess). You can easily give yourself cash as an admin, equip a wallet or briefcase Item and toss the money out to whoever. You can't give someone money that you don't already have.
Well, you should maybe add a paycheck command. I would like to have people obtain a certain amount of money every certain amount of time. I'm sure I can do this easily with events, but it's just a nice idea.
Also, the cash drop is a good idea. Either to drop some of the cash, lose all of it on death, or drop all of it on death.
I wanted to be able to have people lose all of their cash on death in my server that I am building to fend people off from criminal behavior that could get them killed.
