It would greatly improve the user experience to be able to dock dialogs like how the trays dock on Windows. This would include windows like the Ruby Console, and the dynamic components window, as well as other inspector type non-modal dialogs by extensions. I’m proposing this to be entirely an end user feature, with the docking state and position being stored similar to how the window size and position is currently stored. Exposing this to the ruby API would be a bonus but not required.
