Sorry Jeff, my opinion only
No reason to be sorry, Serge! Both options are there for our use. I never said that Qselect wasn't good, I just answered Ron's question about which is more powerful. And I stand by what I said. I will say, however, that I use Qselect far more often than Filter because, as you said, it is less cumbersome.
That being said, NEITHER of them is very good for what the OP was posting about, which is why my lisp works so well for those that have used it
Try using Qselect or Filter, as Ron pointed out, in a drawing with 1 layer ("0"), 10,000 entities with 100 different colors and place each object of each color on it's own layer with the name of the layer matching that color. You'd first have to go through and note which colors are used, create each layer, use Qselect 100 times........just a wee bit too much labor for me.
