Implementing a more flexible and modular panel system in MongoDB Compass would significantly enhance user experience. Allowing users to show or hide panels individually or in groups, perhaps through collapsible panels, docking options, or a visibility menu, would create a cleaner, more focused workspace. Offering predefined layouts and the option to save custom layouts would accommodate different workflows. Furthermore, considering contextual panels that appear only when relevant to the current task would reduce visual density, resulting in a more customizable, efficient, and content-centered interface, benefiting users with diverse preferences and needs.
