The Source List sorts alphabetically. The copy will always sort below the master because it has (Copy) at the end of the name. Focus will remain on the master source and not move to the copy.
I'm very, very familiar with the problem because about 99% of the time that I create a new source I do so by highlighting and copying an existing source. The problem is not really with the sort order. I can happily live with the sort order being the way it is.
It would be better if the copy became highlighted, but even leaving the highlighting with the original source is something I can unhappily live with.
However, what really drives me crazy is what emkaysmith described - that both the original and copy are moved from the top of the screen to the bottom of the screen and the copy is often scrolled all the way off the bottom of the screen. And it's the copy that I will want to use IMMEDIATELY and it's off the screen. The original should stay where it is with the copy as is already the case being immediately below the original except at the top of the screen.
Let me return to my comment that it would be better if the copy became highlighted. As I said, I could live unhappily with the original remaining highlighted if only it would stay at the top of the screen instead of moving to the bottom of the screen. But living with it unhappily is still being unhappy. I can't imagine any universe in which I would make a copy of a source without IMMEDIATELY selecting or editing the new copy. After copying the existing source, I would never have any IMMEDIATE use for the existing source. I made a copy because I plan to use the copy IMMEDIATELY.
This behavior obviously will never change in RM7 and it will be interesting to see how it works in RM8. I would just emphasize that the existing behavior is about as illogical and as counter-intuitive and as user unfriendly as it's possible to be. Maybe the new RM8 user interface will make this particular problem better inherently just because of the improved user interface. But if you make a new source by making a copy of an existing one, the copy should be clearly visible on the screen without the screen jumping around on you like crazy and the copy should be highlighted.
