To build rich and good integrated XRM solution, you will have the need to integrated further buttons.

Actually only maximal 5 buttons are visible directly to the user. All further enabled buttons are moved to the overflow menue
If the button is in the current state not enabled, it is not visible to the user.

Thats changing the user experience in a hard fact, because the buttons are not always on the same location on the screen!

Based on the new full screen mode the form is very broad, and there is enough space for additional buttons, So please make it possible in a supported way to increase the number of visible buttons.
