WKO5 allows the LHE (left-hand explorer) and RHE (right-hand explorer) to auto hide when not needed, increasing the available space for charts and data review. When you need to see the LHE/RHE data or select another workout or range, simply mouse over it, and it will expand to allow selection.
To pin the LHE or RHE to remain open all the time, click the outer edge of it when it is closed (hidden) and drag it to the width you desire. If you are using a PC, you may find it easier to grab the edge if the WKO5 window is resized smaller (not full screen).
To auto hide the LHE or RHE again, click the outer edge of it and drag it to the width you desire.
