The button is platform specific. So if you're on linux, it should show the linux icon. Windows support is on the way. It just entered alpha two weeks ago and we're targeting Beta early october. We record low level windows os calls and replay them on linux in a virtualized environment. Frankly thrilled it works at all :)
Hi Jason, This looks great. Recommend you add an email waitlist for windows version. My team only uses windows. So we cannot try it out till that is released.
