Suggestion: Make a dock from application icons in overview

[Stefano Facchini <stefano facchini gmail com>]

Hi,
maybe this is an already known idea, but it could be possible to make a
dock with the list of application icons on the left side of overview
mode. When the mouse touches the left edge of the screen, the list of
icons slides in, just like a taskbar, without activating the exposé for
windows. I'd really like to see something similar in gnome-shell!

What do you think?
