Shake and Shuffle While Screen's Timed Out?

Question

Is the Shake to Shuffle feature not supposed to work when the screen is timed out?  If so, to me, this is incredibly restrictive.  I'd assume the shake to shuffle feature is added specifically so one can skip the song while performing some other activity - not requiring two hands.  If I have to 'wake' my I-pod when I want to skip a song, why even add the shake to shuffle feature?
For instance.  I bought my Nano specifically to listen to while I go on my long motorcycle rides.  It's great.  I put it on a wristband and run the cord up my jacket.  I'd like to wear it on my left wrist and be able to give my left (clutch-hand) wrist a good shake when I want to skip a song, but I can't, as the screen times out pretty quickly and this disables the feature.
Please, in a future firmware update, can this issue be addressed?  Either by allowing users to turn off the screen time-out, or by allowing a toggle to make the shake to shuffle feature work with the screen timed out?
Thanks

I just found this in the iPod's User Guide: http://manuals.info.apple.com/en_US/iPod_nano_6thgen_User_Guide.pdf
Use “Shake to Shuffle”
When the screen is on, you can give iPod nano a quick shake to skip to a random song. If the screen is off, press the Sleep/Wake button before you shake. “Shake to Shuffle” is on by default, but you can turn it off in Settings > Music.
So what you are experiencing is the default or expected behavior.  If you are up to it, leave feedback to Apple on this using the form in this link.

Is there a setting which will allow me to turn off the sleep feature and just have it go dim?
There is not.
