Dashboard

Hello, So, im recently new to the game(only active playing for a week) and I really really love the game. Like reeaaalllyy. So I rented a small server, and I play with a friend of mine. Now, I misplaced some items(beginners mistake) and the two minutes passed. Now, most of all my ship needs altering, and its not the place the barrier. Is there anyway I can alter the server files to go to creative without taking the server offline? Or should I download the server files, go sp creative in editor (dunno whether it is even possible??) Change what i need, upload the files again and dont have any trouble with personal and player data? Thanks:)

Scratch all, found it, thanks:)
