I often find myself in the situation where I want to add the current directory as a mark or a bmark. The problem is that I want to assign it to a mark that is already in use, but I don't want to overwrite. In those cases I would need to do slight rearrangement of the existing marks and bmarks. We can do almost such thing today with the configuration of vifm and I am looking for a way to do the same with marks and bmarks. Any hints?
