Start menu GUI quirks

1. Press the windows key, the up arrow key and then right arrow (to open All
Programs). Now hold down the up arrow, and every time the cursor scrolls off
the top of the visible menu, it scrolls the entire menu, until the top of
the entire menu (not just the visible menu) is reached, at which point the
cursor moves to the bottom of the entire menu, the visible menu is scrolled
back to the bottom where the cursor is, and the cycle repeats.
But now hold down the down arrow key. Once the cursor reaches the bottom of
the entire menu, it moves to the top of the _visible_ menu; the entire menu
isn't scrolled back to the top.
The problem with this is that if you use the arrow keys to try to select the
item at the very top of the entire All Programs menu, and you accidentally
press the up arrow key one too many times, you can't simply press the down
arrow key once to go back; instead, you have to use the up arrow to scroll
all the way through the entire list again.

2. Remember how in w2k you could use the arrow keys to nagivate submenus
under the programs menu on the start menu, and with the cursor at any point
in any menu, you could use the left arrow to immediately return to the
previous menu. In Vista, this ability is absent. Especially annoying is the
fact that after you press the right arrow key on "All programs" and then
scroll the cursor up or down, you have to manually scroll the cursor down to
the "Back" item at the bottom of the list in order to go back. And not only
will the left arrow key not return to the previous menu unless the cursor is
on the "Back" item, but the left arrow key's behavior is inconsistent in the
rest of the menu as well: if the cursor is on a program (either directly in
All Programs or in some subfolder in All Programs), the left arrow key will
wrap the cursor around to the right column of the Start menu (i.e. where
Documents, Pictures, Control Panel, etc are), but if the cursor is on a
folder in All Programs, the left arrow key does nothing at all.

3. No matter how huge my screen is, and no matter how many items I have in
All Programs, opening the All Programs menu results in a short list of items
with a scroll bar next to it. Versions of Windows prior to Vista were
better, in that they could use all available screen space to give a full
view of the entire menu.
Start menu up/down scroll inconsistency.
And left arrow key doesn't work except on "back" item; it ought to work
anywhere.
