This is a message you have in Sonar, yet I have my two audio clips pasted that would like to apply a crossfade and I still have this message. On the other hand, if I overlap them the crossfade is done, it is either a bug or that's how Sonar works. It's still bizarre as a concept.

How do you mean? If the clips don't overlap there's nothing to crossfade, right?

The Bakery Done, we'll see! 

You had a 1 in 3 three chance of entering the requests in the correct area. Questions was not the correct place. They should have been added to Ideas, one at a time. Adding lists like the one here and http://bakery.cakewalk.com/Question/15761/My-TOP-20-Features-Request-for-SONAR-PLATINUM prevents discussion and voting in individual idea. Some of the ideas are already popular topics in the bakery.

Not sure I understand what message. Do you mean Auto Crossfade?
 
I'd love them to return to original if I pull the clips apart again, like Reaper does.

I think the OP wants to crossfade audio that lives on two tracks. put the tracks next to each other and just fade each one separately not so difficult, really. I can see selecting two clips on different tracks and have a "crossfade" option not entirely unlike the functionality of "bounce to clips" except it just automatically crossfades the overlapping parts of two clips on different tracks.
