As I'm a private game server's hoster, I can answer your question,macros.
The soultions is just two way:money and time.
The server is not offical just a private,so there is no big team to develop it.So if Jill want to make the server become more better,he need more time to develop it,but It will take his more time ,so he cant earn money in RL.
We all know the passion is the best way to insist on one thing like play game or coding,but if the passion faded,what the else to encourage developer? I think the best way is money.lol.
Give the Jill 10000usd per month, I think your suggestion will be release quickly,that's a joke.
So if you want to make the server better,just to give her a kickstart or just to help Jill to coding.-v- Every senior player will give many good suggestion,but a developer need to think more to make there is no serious mistake and use many time to make the suggestion become real.
