It's nice. I tried it out on a mac. The experience leaves something to be desired. The startup time is excessive. It doesn't feel lightweight. When scrolling through a response body the scrolling feels completely different than on every other app on my mac. This must have something to do with java? It seems every "click" of the scroll wheel scrolls by a little more than half a line. Every other app scrolls ~3 lines per click. Keyboard shortcuts seem windows-specific (ctrl-t to open new tab). There are other little things here and there (and some documented on the github page) but overall it's nice. Can't say that it's an improvement over electron.
