I haven't, I'll see if I can find the option
Edit: Never mind, found the option: on the login screen. This is not very intuitive since you can't change or find the option anymore after login in.
The buttons are indeed better like that, I think I would make that default as it doesn't seem to cause too much clutter. However, I still would like a undo of sorts as I sometimes choose builder and then realize that I miscalculated the building costs, etc.
