I like regularly used tools to have a button on the ribbon for quick access. Menu hunting is slow and inconvenient. At this time we can add/remove buttons, however, the sheer size of the **** things severely limits how many can fit before the navigation cube is covered.
Please make an option for half-size buttons in two rows. There is a good reason most programs have many smaller buttons. I know it can make the interface look confusing but as an option for those of us used to it that would be great.
