A multi-event timer for recording (FM or voice) to automate recording start and stop times. Possibly a 10 on/off event timer with a selection for recording 1 date or daily (M-F). Requiring the player to be plugged in, if necessary, would be fine. Sandisk has an entry for elapsed time to stop recording, which is better than nothing but useless to me if forced to record in .wav format, that consumes the internal memory quickly.
