Resize a panel
You can change the size of the panels that appear in the Microsoft Expression Blend workspace. This is useful when you want make your work area larger by reducing the size of the panels, or when you want to view more of the information that appears in the panels by increasing their size.
You can also show or hide all panels at the same time, scale the size of the panels differently relative to the size of the artboard, or just zoom in and out on the artboard. For more information, see the topics that are listed under "See Also".
Move your pointer over the right or left edge of the panel (for vertical panels) or over the top edge of the panel (for horizontal panels). When the horizontal or vertical resizing pointer appears, drag to resize the panel to the dimensions that you want.
Docked panels have a minimum size that you will not be able to scale below.
The category boxes in the Properties panel are not resizable, but a scroll bar on the right side enables you to view all the categories. Additionally, you can expand or collapse categories, and show or hide advanced properties for individual categories.
