I think players should be able to save more than 1 base design. For those who like to switch from one bas type to another. For example, if a player wants to switch from a farming base to defense base and back to a farming base, they do not need to completely change their bases over and over; in the edit base, have an option to load a previously saved base, this enables players to switch from one saved base design to another, with the press of 1 button.
