Gnome In the GNOME bugzilla, there is an ongoing discussion about whether or not to include a patch into the default GNOME installation which would enable GNOME to (optionally) have a global application menubar, similar to that of the Mac OS and KDE (in the latter it is optional and off by default). Installation instructions and .deb packages, as well as a 60-page (and counting) discussion of the patch, are available on the UbuntuForums. Read on for a poll on this issue.

Menubars at the top of the screen are the pedagogical example of the utilization of Fitt's Law.

Fitt's Law is given by:

T = a + b log2(D/W + 1)

Where a and b are empirically-determined constants, D is the distance to the target, W is the size of the target in the direction of travel, and T is the time required to perform the motion.

(http://en.wikipedia.org/wiki/Fitts_law)

Moving the menubar to the top of the screen has the effect of increasing D*, but also has the effect of drastically increasing W (since overshooting the target is not possible), leading to an overall decrease in T. Fitt's law is particularly important for menubars, which tend to have a fairly small height, and thus a very low W unless they are at the edge of the screen.

*) By a moderate amount. It's likely that the tops of most windows are near the top of the screen anyway, so the increase in D is unlikely to be even a factor of 2.
