There are three Devices/Enhancements for purchase in the Shop which are basically to save the player some labour and really nothing more than this. These three are the Golem, One Click God Children and the Professor's Switch System.
The Golem allows you to have Diggy move an object up to 20 spaces at a time (as long as the path is unobstructed) instead of the 1 at a time he normally will do.
The One Click God Children lets the player click on one of the Energy full God Children in their Home Camp or the Camps of their friends/neighbours and collect all the Energy from all of the Energy full God Children there all at once.
The Professor's Switch System allows the player to automatically switch between two different setups of their Camp. Usually if the player has more Camp Equipment than they can fit into the slots they have cleared in their Camp, then they will change the way they have their Camp set up with their Equipment based on whether or not they are playing the game or away from the game for awhile. This means they are putting more of any Energy Regeneration Equipment (the green bar ones) in the slots when they are playing so they can build up Energy quicker, and more of the Capacity Equipment (the blue bar ones) in the slots when they are going to be away from the game for awhile so they can slowly build up larger amounts of Energy during the time they are away. Normally this would mean they would manually have to remove any Equipment from their Camp slots that they didn't want for the other setup and put in the Equipment they did want, then manually change it back when they wanted it the first way again, constantly doing this each time for when they were going to play the game or be away from it for awhile. The Professor's Switch System lets the player automatically switch between two ways they want their Camp set up instead of having to do the manual exchanging of Equipment.
The Professor's Switch System does NOT give the player two different Camps. All it does is allow the player to make two different setups of how they want their Camp for when they are either playing the game or away from it, then switch between them with a click when they want one or the other setup. The player can still change the Equipment in either of those setups whenever they please, and that setup will keep the way they changed it until they change anything in that setup again.
Remember, the only thing these three Devices/Enhancements do is save the player from repeatedly having to do something and nothing more than that. And while that is all they do, not having to spend the time and trouble of constantly having to do those things is really a big deal.
