There is a graphical tool to config, change all its variables, add/remove buttons and sub-panels.
The user can also use TkPanel to change the page when running at some specifics Window Managers, place it at any edge of the screen (thus, really fans of TkPanel can have a few programs running at the same time!), align it at the corners, turn it into a hidden mode, and select what tools to display as buttons (choosing its place). All its functions are available through some keystrokes.
