i have a problem with world downloading and uploading
i have full access to my friend's server but can't remove friend access from anyone
when i try to download/upload a world someone comes and start the server (have permission to start the server only)
and stop the downloading/uploading process
people with permission to start the sever only shouldn't be able to start the server while downloading/uploading
and the start button become gray and change text to (can't start the server right now)
but people with (start) and (worlds) permissions will be able to
the start button will become orange and change text to (can't start the server right now)
with small text under it (a world is being downloaded/uploaded)
if the person clicks the orange button a window appears saying: (do you want to stop the downloading/uploading process)
with 2 options (yes) and (no)
clicking on no will close the window
clicking on yes will stop the process and start the server like normal
wow that was a long thread 
hope everyone likes the idea and thanks for reading
have a nice day
