I would love to see in the Scene manager a popup-choose button with al the available styles in the document, so I can see or/and choose the style belonging to the scene.
Second I like to see in the style manager, when I try to delete a style where it was assigned, a list of scene’s, and with what style I would like to replace it. Because of this , I like to see a red dot or ‘!’ in the Scene tab with a changed style.
I also think the Style manager need some redesign, because the edit button has nothing to do with a selected style in the select area. It edits a style selected in the second style area down under the manager.
