Hi, Tomáš -
Although it is not graphically as slick as what you are accustomed to seeing/using in a browser application, there is a way to do this.
Because the Q&A Editor has been reluctant lately to include any zip file that I attach, I've proactively uploaded the zip file that contains the (hopefully attached) TabDragDrop sample app to my Google Drive:

Since PB already supports DragDrop functionality in the Tab control, implementing this was not too difficult and it did not require much coding. The u_base_tab user object contains the code and behavior.
I hope this meets your needs.
Best regards, John
Thanks a lot, great job as usual!
It will definitely help to achieve our goal.
Best regards,
Tomáš
