1. After pasting object(s) make the object(s) already selected. Not the one you copied if they are from the same screen.
2. When using a mutli object selection in a screen : Allow the use of ctrl key+ click to deselect object(s) at least in the left "Screen Objects" panel, ideally also in the WYSIWYG too. Would help a lot when objects are entangle. Select the area in the WYSIWYG, deselect the object you don't want.
Currently you have ctrl+click in the from the start in the left panel and pray you don't select a wrong well named "Cartesian" !
