XYplorer Beta Club

I tried XYplorer 16.00. The "Add new items at the end of the list" option has no effect, isn't it?
New items are still sorted to the list when drag file from one pane to another pane
OR copy in one tab and paste in another tab.

"New" is meant here in the sense "newly created", i.e. by using any of the "New ..." commands. What you want is not supported.
