I run a large company, and like most people, use our company website as a portal to many different password protected sites, ftp file servers, news feeds, portfolio and engineering documentation. I use a couple of different PC's running W10, mostly fast laptops, in different locations.
I frequently restart from scratch, use a very wide variety of wifi, including my phone.
I need a home button, a bookmark list, and the speed dial page gone. All of your workarounds are solving an already solved problem. I guess that is great if you get paid by the hour or line, or whatever. When I boot, I select the browser I want to use (usually FF or Opera, occasionally chrome if I need to cast, since it works well for that. If I wanted a list of all the sites I just visited, I will use history. If I wanted a list of them graphically displayed, I would love it, I bet kids do. (speed dial) I want to press a browser to select it, and I want it to give me the freshest capture of the site I have selected as my home page. If I close it, because I am at one of the hundreds of sites I use each week, I usually just hit the home button, because guess what, I have the freshest view of the most important website. I picked it.
As the touch screen has basically died and gone to FOX news, because a mouse or pad is so much more efficient for work, so too will this petty display of technical wizardry. It is simply not useful. Seems like it would drive development, but the kids love their toys.
