in my university Moodle I am docking all commands to have more space on the screen for editing. But there is one thing which I cannot dock (or hide) and which prevents the entire left-hand side of the page from useful contents - it is the "Add a block" component. Which is really painful since in edit mode Moodle displays many additional commands/information on the screen thus making every pixel of the screen even more precious - and here entire column is completely useless. How can I dock the 'Add a block' component? Any help would be appreciated!
Here is a screenshot from my course to illustrate my problem:
