> The problem with all these desktop UI toolkits is they have a look and feel all of their own (IMHO). You can make buttons look like Windows buttons on Windows and OSX buttons on OSX but that's only superficially cross-platform. Exactly this -- every cross platform GUI toolkit ends up falling into an uncanny valley where it looks sort of native but subtle things are just off. This is, I think, a key part of Electron's popularity. Apps made with Electron are so very obviously non-native that they avoid this uncanny valley effect.
