It's a waste of time to debate the usefulness or reliability of keyboard shortcuts; some people don't use them and spend their drafting hours navigating drop-down menus. Quite honestly, in the four days I've been using 2013, I'm almost as fast with the new method.
For me, the question still remains: Why remove the fillet dialog, but not the offset dialog? Where's the consistency in design and implementation in this software? I've been using VW for 9 years, and I'm a big fan, but this lack of uniformity in execution is puzzling. (Did they mean to remove the offset dialog, but forgot? Did the fillet dialog get overlooked? Are all dialogs on the chopping block in future, more robust upgrades?)
