Nope. After that skin, it will still be a flyout menu. That is its distinguishing factor from other hundred replacements and isn't going to change because Vista/7 style restricts all programs to a too limited area for browsing with mouse. Of course, if you wish you search, then it's similar but again, not the same. If there are MANY search results, Classic Shell can show them in multiple columns, no scrolling required. It's open source, you are free to modify it as you want and fork it.
In fact, one unique feature of Classic Shell on Windows 7 and Vista is that it turns the Vista/7 style menu also into a flyout menu. Go to the "Windows Start Menu" tab and check the "Cascading All Programs menu" option.
When I started using Windows 98 (up from 3.11), I thought that the flyout menu was pretty cool. (Although almost anything was better than Program Manager...) And I stil think it's neat to see them pop out the side like that.
But honestly, over the years it got to be a growing annoyance that the menus would cover up a big part of my screen, and I had to be so careful to put my mouse pointer over the exact spot lest I end up with an unwanted menu. So when the Vista menu made its appearance, I welcomed the change.
In my personal order of preference, it's the Vista/7 menu on the top rung, then the classic menu, and -- way, way below -- the Metro start screen. (Hmm, it just hit me that the Metro screen is a bit like Program Manager, with the links to the various programs displayed in a grid when you first boot into Windows. And, like with 3.11, in a Metro-only environment -- such as they're pushing with Windows RT -- when you have a program open you can't tell at a glance what other programs are open. But I must stop here, as my own rule is that this isn't a thread for comparing the Metro start screen to the start button/menu...)
What I like the best about ClassicShell is the separate feature that brings back most of the functionality of the IE status bar.
