Collapsable Sidebar
More space on every page.
It would be nice if the navivation-bar can be collapsed to get more space for the rest of the page. Eventually it can be done in a fashion like on code.google.com/webtoolkit/doc/1.6/DevGuide.html. There the navigation on the left site can be collapsed.
In addition to this. If the navigation is collapsed, there should be a few icons in the header (between login-name and search-field) that are the main navigation-points(daily-use) for the loged-in user (ex. Team-Member (Dashboard,Sprint-Whiteboard), PO (Dashboard,Produkt-Backlog,Issues))
