Brilliant!

A worthy successor/evolution to Basecamp2, and a very powerful collaboration/project management tool it is indeed. I love the consistency between all vectors off service access, be it iOS, the Mac app (finally! W00T), or via web browser. All are clean and fairly straightforward to use. Even if there are a few niggles here or there, this app and service are living proof that basecamp has been making steady consistent progress and improvement without feature creep for years. One small suggestion going forward is making the notification preferences easier to get to, right now I have to click the "work can wait" hyperlink under time zone to get there. Bravo!
