I'm always a bit surprised there was the space for Electron to exist in the first place. Since most operating systems have widget toolkits that have browsers effectively embedded into them.
What I would have liked to have seen instead of Electron would have been a shim API that abstracted OSX/iOS/WinForms/QT webviews, and for those webviews to have a working API that would allow DOM manipulation, and allowed native sub-views to be inserted as block elements.
One reason is that for a very long time, if you created a native WebView on Windows, you would get an IE7-compatible browser, even if the user had installed a much newer version of IE. There were a couple of tricks you could use to get the user's actual browser version, which I described some time ago here:
In any case you were still dependent on IE10/11 at the best, and certainly nothing as modern as the old Edge, much less the Chromium-based Edge. And on older Windows versions it completely depended on whether the user had upgraded IE.
You could write HTML/CSS/JS that was portable between IE10/11 and other native browsers, just as we all did in actual websites. I did this for Mac/Windows in the past and it worked, but it was fairly compelling for web developers to have a single browser version to target instead of the various incompatible native web views.
The situation is a bit different now, where you can get an Chromium Edge view on Windows 10 and a Safari view on Mac, but what do you get on Linux? I don't know.
You had to use JavaScript or VBScript but all the safety rails are off, this is pre-sand boxing, what do you mean websites might be malicious why would someone make one like that... you could do crazy things, and fully leverage windows APIs directly without much effort via VBScript, I once used the winforms(?) APIs to introspect field labels and names to automate the driving of multiple desktop apps from a crazy jquery and VBScript monstrosity. Made me twice as efficient at that job though so it was awesome.
You could control child iframes and pop up windows (remember these?) and VBScript let you shoehorn quite a bit of native UI type stuff whenever it was going to be easier than building something with simple forms, JavaScript, tables and frames. If you got really fancy you would Base64 some absurd binary into your app and unpack it on the fly with VBScript then call it from a temp directory in order to drive things like interacting with network services that didn’t have any sort of thing you could work with via HTML JavaScript and XMlHTTRequest (this was the very dawn of Ajax)
