Opurt writes: On the first day of the Ubuntu Developer Summit in Boston this week, a roundtable session focused on the vision for the upcoming Hardy Heron Ubuntu release. Unlike Gutsy Gibbon, which brought a handful of experimental features along with some new functionality, the focus with Heron will be on robustness as it will be supported on the desktop for 3 years. 'The Compiz window manager, which adds sophisticated visual effects to the Ubuntu user interface, will be a big target for usability improvements. Keyboard bindings and session management were noted as two areas where Compiz still needs some work.' PolicyKit and Tracker will also be significantly tweaked, while Heron is also likely to see a complete visual refresh.
