Hello, thank you for the message and the evaluation. Not exactly sure of what you mean by "dragging and dropping urls", as the function already exists. If you could specify a little more ?

Right now, one can drag:
- a tab URL, by dragging from the tab bar at top of the page
- the address bar URL, by dragging the (i) icon at top left
- a link URL in a page, by dragging the link itself
- a bookmark from the tree
and drop wherever needed in the bookmark tree.
Let me know if there is anything else draggable that I missed, and I'll look to add.
