Ability to change between the old and the new transform tool setup in the game settings.

Some people like the old transform tool and found that it was quicker for them to be able to both move and rotate to get shapes in the correct spot.
Some people like the new transform tool and find that it works better for them being able to move or rotate without accidently doing the opposite action.

I found that for me I like to get the positions of objects perfect when I build, so I would have to switch between the move and rotate frequently so I could get it perfect. By having a setting in the game, it will allow for the player to choose which way they prefer and if they wanted to switch at any time, they could switch by using the in-game settings.
