You could add -- * a popup which modifies the color but this does not solve the -- * fact that it still requires a lot of cluttered space to do. -- * -- * In these kind of instance abstract comboboxes are quite handy. All -- * value modifiers are hidden inside the combobox popup and only -- * the color is shown if not open. This combines the clarity of the -- * popup with the ease of use of just using the space for modifiers. -- * -- * Other instances are for example time and especially date picker, -- * which only show
