I need a feature that can enable you to group your side bar into folders when they become too much. Say for example, I can drag and drop all my workspaces into one folder. All my social media side bar pages into a folder and name it say Social Media, If I also use side bars to access my emails, I can as well add them and say Emails etc.

There should also be a feature to easily add any webpage of your choice to the opera side bar with ease. The option that is currently available is not as good as it should be. One has to access it via some hidden settings.
