The Google+ redesign from last week may look pretty, but it's also missing a lot of features that were available in the classic layout. This is true of every product revamp or relaunch: there will always be a tradeoff between getting all the bells and whistles of the new version and keeping the things you're used to on the old one. There's a whole help page that lays out most of the changes and features that the redesign still lacks, ranging from the simplification of profile pages to the (temporary) removal of polls from the web version. Fortunately, upgrading is still entirely optional, so for now you can stick with the classic version of Google+ if that suits you better.
