Expand Board for macOS

Expand is a spatial board for macOS. Place text, images, files, and shapes on an open canvas, then nest boards you can actually go into. Double-click the board to add something. Right-click to choose text, images, files, or shapes. The plus in the toolbar adds from the top of the window. Drag to arrange. Open a board to work inside it, then use the title-bar breadcrumbs to go back up.
