I'm really impressed so far, it's almost like Amethyst lite. Keeps most the functionality but in a less convoluted way. I like the power user aspect of Amethyst but what Wisp does keep it's packaged in an simplified, intuitive way.
It's familiar enough for me to not feel like a jarring client switch and more like slipping into a snappier version of something I already know. Great UI layout.
The best part is I don't have to settle for one or the other. It has been a good two days Wisping around though. ๐ซก
