Bob,
The writing and loading file features that you just introduced in JSmol are
truly innovative and take JSmol to a new level. Excellent job.
However, I do have one aesthetic suggestion:
When loading files into JSmol from a local machine, a new panel with
BROWSE/LOAD/CANCEL buttons appears on the page and a prompt window only
appears after clicking on the BROWSE button. Is it possible to go straight
to the prompt window (as happens with Jmol when loading a file) to select a
file of your choice in lieu of having to go through the BROWSE button? Just
some thoughts.
Thanks!
Amjad
