It would be really slick to have a few different user-definable
configurations for the shortcut bar. The user could create new
configurations, then add a few buttons, and then switch bars
depending on their mood.
For example, I could have a "games" bar that would have
various seek and formula buttons. I could also have a "mamer"
bar that would have mamer commands on it. Note that only one
configuration would be visible at a time.
