What I want to see in the next gen of SACD players

I was listening to a few SACD's the other night that I have owned for a while. With few exceptions I prefer the sound of most multi-channel CD's in the SACD stereo mode. I decided to do further comparisons between 2-channel and multi-channel on 3 SACD's. Elton John's GYBR, The Allman Brothers Eat a Peach and The Who's Tommy. All three of these I have stated in previous posts sound better in stereo as opposed to multi-channel. Overall, I still feel that way but on further review I found I liked some songs on those CD's better in multi-channel than two channel. Say 2-3 songs on each CD that sounded great in multi-channel with all the others sounding better in 2-channel. This sets up my next point.
I would really like to see SACD players have the ability to "memorize" a preference for a particular disc. In other words, be able to program those one or two songs to automatically play in multi-channel with the others in 2-channel. Currently I have to stop the CD, push the button for multi-channel and then restart the CD over again.
Another function I'd like to see with SACD (and DVD video) is the "marriage" between these two formats. NOT in the DVDA envisionment where there is video content on a music "album" but rather motion pictures whose audio has been mastered/re-mastered in SACD. It seems the next generation of DVD players that will do hi-def (blu-ray for example) should use an SACD sountrack to go with the picture. This would "eliminate" the need for Dolby Digital or DTS I would think while providing better quality audio! And with Sony being the major backer of Blu-Ray you'd think this would be a no-brainer!
Anyway, this is what I want my next SACD player and/or DVD-SACD player to do! What else would you like to see in the next generation of SACD players?
