I'm suggesting the ability to store up boosters for use whenever. Players will already be able to buy boosters as soon as another booster ends, so this will be more convenient and encourage users to spend more money on the server. People will not be required to wait for another booster to end to buy a booster themselves. All the boosters would go in a list (accessed through something like /boosters) and there could be a command such as "/boosterenable donation" for the donation sale booster, or for the suggested SG kit-free booster, "/boosterenable kitfree" or something such as that. This way someone could buy 10 donation boosters, but they wouldn't be used at once, rather when the player decided he/she wanted to use a booster. Also, as an alternative, boosters could have a queue-type setup where as many boosters as one wants can be purchased, but they just go in a queue similar to auction. So if someone bought a booster and then another person bought a booster while the other booster was active, it would just go in a queue and the total time the booster lasts will be 20 minutes instead of 10. I'm not sure how coding either of these would work. I just figured that people are already able to buy boosters as soon as the previous one has ended (to my knowledge) and that this would be more convenient to those funding the server.
I would very much like to see this, and it should not be altogether that difficult to code once boosters become availible. +1
