Will there be any new features in Drupal 7 for the registered members/visitors to our site ?
Not something for Administrators, not something which was already in contrib and brought to core or partially or poorly implemented in core etc - I mean to say something "bell and whistle" but not exactly so frill-bee like bells, something unique and useful which can be gift to the members and unique or compelling reason to use 7, something which matters as NEW and innovative to our site's ultimate end users ?
Some appropriate or inappropriate examples can be
Tabbed browsing when it was first brought by Opera
Incognito browsing tab when it was first brought by Chrome
Shiny new Social profile out of the box brought by vbulletin and invision
Last comment view and optional reply to that on hover in Blursoft forum
Book (or wiki) and Forum OOB when they were introduced first by Drupal
Any such list for Drupal seven ?
