please neglect the attachement; it was done by mistake and cannot be removed.

As mentioned already several time the sidebar is great. It increases the usable area of modern PC screens. The MS Ribbons do the opposite.

Problem description: 
Depending on which icons one is using, there is still one or more traditional toolbars needed. On the other side there is space left in the sidebar or not every user needs all icons of the sidebar.

Enhancement request
Make the sidebar customizable as the traditional toolbars. This would make the sidebar even better than it is already. This should also include the possibility to tho resize icons like the one for lines, colors, etc.
Operating System: All
