(I'm all ears on how to solve that file picker problem though, that is mildly annoying).

Obviously this varies from person to person but I have verified already a more than a decade ago that it worked very well with ordinary users as long as they didn't need MS Office or anything like it.

And true: Netflix doesn't work but for that I use my phone/tablet that I cast to my TV.

You may say: not everyone has a PC and a phone but as far as I can see the overwhelming majority who has a PC also seems to have a smartphone.

You only have a directory file tree, that is often not in the right directory, where the application was launched from. No really way to directly jump to a directory via a path, that you copied from a open Explorer, which you might have open next to it, because you started the .exe from there. So you have to click your way through.
