Server Profiles
This idea come primarily out of laziness but it's a fairly simple concept.
A new "profile" command when setting up a server
Say you want to set up a betting server? You can just do something like /lsp bet
which would automatically set the server's gamerules to whatever the person had predefined them as.
eg; betframes, minbet, maxclients
It would shave off a few minutes off setting a server.
