shifting buttons to change the order

[stefaniehoechtl]

Problem:
For some users it might be important to be able to determine the order of the buttons (e.g. to have the most commonly used buttons at first, rarely used ones at the end).

Solution:
Enable shifting buttons to change the order.
The users would like to:

• use Drag & Drop
• have a button called "enable shift"
• (perhaps right-hand click - "shift" to maintain the consistency?)

Issue resolved if:
The user can determine the order of the buttons.
