Kagi Windows user here. As it currently stands, I don't really have a reason to support Orion+ with a lifetime account since I can't even use the product, though I'd love to the moment Windows is supported. Will the Windows version of Orion be WebKit-based too? That would definitely be a good way to differentiate yourselves from the competition as I am not aware of any browsers actively developed on WebKit for Windows. Not sure if there's a reason for that or if it's just the status quo.
Are you willing to swap out rendering engines based on the OS it's being built for? If so, how would affected development in regards to fragmentation? Much appreciated.
