It would be good to have more control for organisation and management of bookmarks (views) as the title of the post suggests. We have currently over 50 bookmarks in a current project that covers multiple sites over a large geographic extent. It would be good to have the ability to group and have subgroups of bookmarks similar to the scene navigator; and additional for the save snapshot button to be separate so you don't have to scroll all the way down in order to export the view.
