What is a dockable pane?

A dockable pane is a user interface element that can be moved and rearranged within an application window, allowing users to customize their workspace. Typically, these panes can be docked to the edges of the main window, floated as separate Windows, or minimized for later use. This feature enhances usability by providing quick access to tools and information while maintaining a flexible layout. Dockable panes are commonly found in software applications like integrated development environments (IDEs) and graphic design programs.
