Two options have been added to reset the size of the panels in the Sidebar:
1. "View" → "Side Bar" → "Resize Panels"
The Resize Panels option adjusts your panels in the side bar area down to equal sizes within the viewable area of the Side Bar.
2. "View" → "Side Bar" → "Collapse Panels"
The Collapse Panels option minimizes all of the panels in the side bar area to their collapsed state.
Once either of these options are used, the user can then resize the panels to any desirable size. Panels are resized by clicking on the upper edge of the blue panel header and dragging it up or down to make the panel large or smaller.
