99.9% of users have no idea they are inside a web frame. And so what if a good app uses 100-200M of ram these days? That's like one tab in Chrome. Electron has very low idle CPU usage, which I think impacts more users than does the memory. Each of those cross-platform widget toolkits look like shit.

The bigger issue is obviously lazy developers not polishing their electron app, but you can do basically anything with it.

The question is - why? (besides not learning right tools) From app I want intuitive UI/UX, that means I want that raw gray "win95 look" controls, be it button or tree... I don't want some monstrous CSS/HTML crap.
