@coderpatsy Thanks for the hint Command-right mouse click works. Is there any binding to exchange an item from the quickbar to the hand , like it worked in the stable version?

Problem is, there is no middle click on a mac. It wouldn't be a problem, if you could replace an item by a different one, but so you end up with a quick bar filled with doublets.

On MacOS 10.13.6 you can add items multiple times to the quick bar, but you cant replace them or take them off
