Win 7 needs an icon that lets you half screen any program.
You're entitled to your opinion. But you can just hit the Windows
key plus the left or right arrow and get that result now.
It also needs an icon to keep any program on top.
Right, because then you will miss popup alerts, like your laptop
battery is low and you need to plug in or risk losing your data.
It also needs an icon that
will allow a video player to display minimum view.
Why should that be a Windows issue? It sounds like an issue of your
chosen video player. (If my "minimum view" you really mean minimize
to taskbar, press Alt+space, then n.)
What Windows does *not* need is more icons. Our desktops are
cluttered enough already, though Windows 7 at least makes it easier
to remove some of the clutter.
