Suppose I have two boxes joined by an arrow, as the picture shows:
I would like to be able to move each one of the boxes independently in such a way that the arrow is still joining them in exactly the same position (mid points of the sides). I have been exploring the "join nodes" tools but I have not been able to succeed in that.
A similar question can be found here, however, it has been asked for Adobe Illustrator, and not for Inkscape. Anyway, according to the answers there it seems this is a limitation of the format itself, but I just wanted to be sure.
