Expand the left flyout to the last open position with a single click. Remove the step that expands the list of icons without opening a panel (such as Pages or Bookmarks).

Currently, the left flyout can be collapsed with a single click but requires two clicks to reopen the Bookmarks panel (one to expand the list of panels and the second to open the Bookmarks). Given that the list of icons is always available when a panel is open and that users typically return to the same panel once a panel is open, requiring the second click is extremely inefficient and ergonomically undesirable (less clicks are better for our hands).

For example, I use the Bookmarks panel to frequently switch between drawings as an Engineer. I then need to collapse the panel to maximize the view of the drawing for readability. In some situations, this change could reduce clicks by as much as 5-10 clicks per minute, which is a significant efficiency and ergonomic improvement.
