Behavior of Gradient Editor dialog

When selecting an object with gradient applied, the "Fill and Stroke" panel responds predictably. This isn't so with the "Gradient editor" dialog, which appears not-dockable (floating, despite how preferences are set). That fact isn't so much a problem as the behavior of the dialog; it neither changes nor closes on its own when I change my selection.

When I select another object with (or without) gradient-fill, shouldn't Gradient Editor change as well?

As a proposal, the Gradient Editor should be responsive to the currently selected object. When the object is a type of graident-fill, the editor should reflect the assigned gradient as the object is selected, much like "Stroke and Fill" already does. When the object is a non-gradient or "null" fill, the dialog should be disabled (grayed-out).

Overall, I wonder why the Gradient Editor is not a sub-group or tab of the "Fill and Stroke" panel. To me, that would make infinitely more sense.

I could understand the preference to have a Gradient Editor persistently open to adjust one gradient, but shouldn't that be a "pin gradient" or similar feature? When selection changes to a different object, I would expect the dialog to change.

Thank you for making a truly valuable open-source illustration tool, keep up the good work!
