Because of the potential issues horizontal navigation introduces in

do report cases that don't work, or which are not precisely and

I'd like to know if you have a spec or guideline for how to use horizontal menu elements.
The Sound Menu wiki didn't specify anything about horizontal menu elements, the only reference is this mail of yours..
What i know so far about how to design with horizontal elements:
* use only where necessary
* try to design for easy pointer-aiming ( as few horizontal elements as possible)
* look out for cases of mutual exclusion to help reduce the number of simultaneously displayed items
* use for frequently accessed controls that must be close to each other
* use for controls that have a special semantic proximity (e.g. backward, pause/play, forward)
looking through the Indicator Menus, i found 2 places where horizontal elements were being used so far, both in the Sound Menu:
a) the volume bar with the Mute button (loudspeaker with no waves), Fader, Full Volume Button (loudspeaker with three waves).
b) playback controls
what can we deduct from this?
First of all, that we have two Mute buttons in the Sound Menu...
Second: It *is* possible to design a comfortable menu interaction experience with horizontal elements.
