The places panel can't really deal with a bigger (huge) number of places.
A bookmarks menu (same as in Konsole) should be added to Dolphin, so that the user can create bookmarks in addition to places.

Benefits:

• User can keep the places panel small and clear (only import bookmarks as places)
• User can efficiently create/sort/categorize a huge number of bookmarks with the help of the bookmarks editor
• User can bookmark multiple tabs into a bookmark folder
• User can open multiple bookmarks of one bookmark folder in multiple tabs

This targets advanced users.
