I missed the extra level of hierarchy. At first glance, it looked like the previous text--sorry.
FWIW, this seems like a pointless complication. The sleep timer isn't a system date/time function--it's a playback-related function, because it's reset every time you restart the player. This is similar to a bookmark and should be at a higher menu level, not a lower one.
Was there a good reason for moving this feature? Is there a chance it could be put back where it's been?
Anyway, thanks for the help.
