I highly recommend backing up your world or testing this mod out in a new single player world before first use in case unforeseen issues come up.
Although I have yet to find any after testing this alongside over 100 mods, let me know if you run into any issues. The 1.18.2 update made accessing world generation stuff easier again so I have interesting new plans for this coming update.
This mod allows users to teleport to and from a separate dimension using the /create command where they can test out mods or design ideas before implementing them in any additional dimensions without having to worry about affecting them just to figure something out. It also provides some security functionality that saves the user's original inventory and clears it in order to replace the creative inventory upon exiting the dimension by any means and ensures anyone without an elevated permission level return to their original gamemode for use on servers.
