You can adjust the size of your sidebar to create more space for the page you're viewing. Similarly, if your sidebar only shows icons without labels, you can expand it to fully display the menu. Here are two ways to do it:

If your sidebar is minimized, click the cogwheel icon ('Settings') in the bottom-left corner of any Chess.com page, then select 'Expand.' This will restore the full sidebar with both icons and labels.

To minimize the sidebar again, repeat the same steps and select 'Collapse.'

If your sidebar isn’t fully visible and the 'Collapse/Expand' icon is missing, your browser window may be too small. To fix this, drag the edges of the window outward, click the square icon next to the 'X' in the top-right corner, or double-click the navigation bar to enlarge it.

This should either display the full sidebar automatically or reveal the 'Expand' icon, allowing you to adjust it manually.
