The new navigation gives clearer context, especially for workspaces that have projects. It has a modern look and feel and gives you more room for your work by decluttering the navigation interface. Over the next few moths we will be rolling it out for all users. Right now users can choose to test the new navigation and with the February release we also make it standard for new users. We have also fixed some minor problems for specific use cases of Webforum with the new navigation.
