Problem description

You want to free screen estate and use amini/slim drawer, but you want it to expand when it is focused and on mouse over.

Solution

Nothing very complex, you just need:

• a flag variable for the mini state of the drawer
• a flag variable for when a menu from the drawer is opened.
• only display the mini menu when it should be mini and there is no menu open
