>Step 1: People realise that Electron apps look different and do not fit the OS.This is not an issue for most people. I like to use Spotify (the desktop app) as an example - it's a pretty good looking app, works nicely, and yet it uses an HTML-based UI.
Microsoft's own UWP also looks vastly different than native Win32-based apps.
The resource usage and slowness of Electron apps is a problem, but that is caused by using the entire browser runtime. When it comes to the capabilities of a UI framework, one of the questions I ask is "Could you build something like Spotify's UI with this? How difficult would it be?".
