I didn't know that the current INSERT feature did this, but yes, my proposed insert would work just like this; Whereby subsequent inserts would be inserted right after previous ones.

This raises an interesting point about INSERT SHUFFLED, though.

If you selected x and use INSERT SHUFFLED, it would be shuffled, then inserted.
But on subsequent selection of y,
is y shuffled then inserted after the shuffled list of x or
is y shuffled with the previously INSERT SHUFFLED contents of x

?

good one.
