Could you add the ability to define portal frames and lighting implements to travel to dimensions added by this mod? While the current state of the mod works for server admins who can use command blocks and such, it does not lend itself to use for modpacks since the only way to travel to the new dimensions is via command.

This is planned as its own separate mod, called "JSON Portals". I also started on it a little bit already back in last summer/fall, but then it was left in the back burner due to me always working on other mods instead... So it is coming, if only I had time to work on it :/
