Need more space for the 3 boards?
You can collapse the blue side menu by clicking on the SquidHub logo in the top left corner. This will give you more space for content in the main area with the 3 boards.
You can expand the sidebar again bar clicking the "hamburger" icon in the top left corner.
You'll see the icons for each group to help you navigate between groups when you have minimized the sidebar.
Note: You can also collapse and expand each of the 3 boards inside a group. You do so by clicking the minus icon next to the board heading.
