Not sure what your issue is.. I can't recreate it.
When copying/moving using Drag and drop on the same drives the default action is Move.
When I recerate it I just select some files and then drop them into a sub folder in the same panel.
( Btw No. hotkeys are faster and simpler if you know how to use it
And you do not have to move the mouse and hit exact points.. but if you are not used to keyboard navigation and its hotkeys it can ofcourse be more complicted and not so simple to use, So thats why drag and drop is also supported..)
