[Klaus Holler <kho@xxxxxx>]

Hello Jaap + List,

please find attached a small patch (against zim-0.65.tar.gz) that 
enables Drag and Drop support from the PathBar into the PageView - a 
link to the dragged Page is inserted then.

That was a feature which I did miss up to now - to be able to directly 
add a page link into a page by drag and dropping one of the just visited 
pages from the PathBar at the top. This is especially useful if the page 
you are editing right now and the ones which you have visited before are 
located far away from each other in the page index, but you want to link 
them.

Kind regards,
Klaus
