there is also a way to do this using documented features with a little
add-on tcl script. please find attached a script command, that i per
default hook into my VMD Tcl interpreter that will check the list of
loaded files of the current molecule, delete all frames, and then
reload the last file into the existing visualization. to not disrupt
the visualization, it first stores away the view state and then after
loading will re-apply. it should be straightforward to convert this to
a command loading a new molecule without messing up the view.
