I think all of the people thar creates on 1.0 really have experienced this: You are creating terrain or something, but you can’t continue because of the border.
I have a suggestion to fix this:
A new island called “No Limits” would be able to be chosen on the islands browser. To be compatible with multiplayer, would be needed to use the IP / collab island sistem. All players might need to accept the teleport to that island, so the only island that exists is one, the “No Limits” island. This should be done because if not, the island would colapse with other player’s islands if you play with more people.
On this island only would be an small plattform that can easily be deleted with the mobile.
This sistem would be really useful for big maps like Battle royales, RPGs…
