In line with their recent trend of developing for all platforms, Microsoft has quietly released a semi-private beta of a launcher app called Arrow. The early release sports an interface reminiscent of Aviate, but appears less devoted to contextual recommendations. While the current version is fairly basic, the big ideas may still be on the horizon.

The first thing I noticed is that Arrow replaced the stock icons for system apps like Phone and Messages, which isn't in and of itself a bad thing but an unexpected behavior.
