edge reflow is an application designed to allow for development of responsive web design. similarly to adobe muse, edge reflow design is based on the visual layout of a web page, rather than the code that makes it up. this was a completely new tool, rather than a reworking of an old application, or one acquired by adobe. the initial preview was made available to the public in february 2013, after being announced with the rest of the edge suite in 2012.
