I humbly disagree. The main feature that the start menu lacks is folders. This to me is just obvious. The thing I dislike the most about 8 and 10 start menu, is how difficult it can sometimes be to find/distinguish apps from one another. Native apps sit on square similar colored tiles with just a teeny tiny icon on them along with their name(to be fair, the size of this icon has grown a little bit over time). It can take a little while to distinguish apps from each other with this recipe, and it does even when you know pretty much where you are going. You have to look around a bit. I know there are a lot of ways to skin a cat in Windows, and that you can link to apps on desktop, and taskbar for ease of use. Still, why create the slick new start menu if you aren't going to make it 100% useful. As it stands, I find myself installing rocketdock, and linking to main apps on desktop/taskbar, rarely using the actual start menu which was supposed to be one of 8 and 10's biggest new features. I have yet to own a 10 tablet, but if I did, I'd probably be clamoring even louder for this suggestion to get coded in. We need more emphasis on the icon, or better yet, 100% emphasis on the icon, we'd be a lot better off at least as far as the start menu goes.

Even more than this though, beyond the generic visual aesthetic of native app tiles, I crave the ability to organize my apps in folders on the start menu, and have them fan out in a visually pleasing way when opened, without actually leaving the start menu until an actual app is opened. I don't want to have to have an always present link to all of my apps along a massive grid (with groupings sure, but every app must always be visible) that may span a screen or two. Combine this fact with the generic nature of the native app tiles I discussed in the first paragraph, and it just adds to the search and hunt nature of the current start menu. Give us folders. Let me have my main 5-6 apps with their own links, and then beyond that, a folder for tools, another for finance, a 3rd for music apps, a 4th for social apps, things like that. I know you can put a folder on the start menu, fill it with shortcuts to apps, and have it launch in explorer. This is a 'workaround', it ain't slick. It isn't modern. Android and IOS have this feature built into their launcher, and have had it pretty much from the beginning. So did blackberry. It really can't be that hard to code.

Anyways, this is imo, the main missing feature of the Windows Start menu and has been since the beginning.
