won't be really hard to improve the market share:
- make edge cross platform.
- make the extensions system on par with chromes and as easy to launch an extension
- fix its UI lag on Windows 10
- maybe open source it
The rest I'm not really sure that there is much benefit to it save the UI lag fix. The oft-tossed about technical debt is incredibly real with Microsoft's browsers, and I believe a lot of the debt that IE had was inherited by Edge to ensure a transition for Microsoft's clientele relying on the IE support for their sites.
Unless Microsoft wants to branch into having a "business browser" and a "consumer browser", they can't give users a clean and non-burdened version of a Microsoft Internet Browser. I really doubt they're going to want to deal with the headache of splitting the focus to two versions. They can make all the changes they want public facing, but as long as they have a sacrosanct part of the browser that can't be altered or removed, they're destined to be an afterthought if a thought at all.
p.s. when the page loads in Edge its actually quite fast and scrolling feels smoother than other browsers - but the initial delay breaks the whole experience for me.
I'll admit that I don't actually like edge's scrolling very much, I think it's the [de/ac]celeration curves - but that's a purely preference thing.
