I didn't say anything about table sorting. I'm talking about sorting of layers and the elements in the layers dialog.
If you can drag& drop elements and layers the layout should also be saved shouldn't it?
I mean layer sorting
If i drag N drop layers?
drag and drop to where?
if you mean change there order, it would be kind of nice, but not necessary in the short term
it would be something you could slate for a post release update or something
10.7 has not done it up to now, and i can not say it was a feature that i thought about too much, only on occasion
I dont think there would be a mutiny if that specific thing was done in a minor update, when you have time to just deal with it alone?
I can not think of anything else one might drag and drop a layer for, surely do not want to drop a layer inside another layer 
Dragging and dropping element.
Seems we could always drag an element from layer A to layer B? in 10.7 anyways, i can all the way back to revision 4356 anyways, i dont have any older revisions still on the PC
as far as like trying to redo their visual order in the layer
I myself have never terribly felt the need to do so.
But that may also be because i have 80+ layers and so not much call to try resorting the things in a layer because there are not that many elements per layer.
That is not to say that someone, or a lot of someones might not put that to use, it just has not come up as a need for me because i have things so sub categorized
that i dont really have much to sort in a given layer.
But if it is one of those things where it is "Cool New Feature" but is keeping you from being able to finalize 10.7 and the feature simply needs more time and testing
i do not personally see anything terrible about holding that specific feature back so it can have some dedicated time by itself to be worked on and released in like a 10.7.1 update
or something.
I know you arent exactly sitting there with 24 hours of day and nothing at all to do with it every day
