This is doable. However, there was discussion on this point for the current
TclTk gui (where it is also doable). The majority of the responders
preferred to be able to add and manage layers without waiting for a redraw
for each change. They preferred to control redraw.

Duly noted. Multiple drag and drop is more difficult however.

Definitely agree. We've discussed adding these when basic features are
working well. For example, a contextual menu for a display might list
various zoom options, redraw, etc.

I tried the sliders and they looked bad (at least on my Mac) and took up an
inordinate amount of space. A bonus of the spin controls is that you can
type values into them too.

This requires a custom options dialog because it actually calls d.his. I
think this is a very handy feature. But right now, we're using the
autogenerated dialogs for each command to save time getting the GUI up and
running--and these are actually quite nice. We've talked some about custom
properties dialogs in the future.

This is using your default system font. One problem with specifying fonts
in detail is that they may look funny or even not work on different systems.
Currently, I think the font is 11 point, which is a pretty good compromise
on most systems. Which part looks especially large to you?

Thanks for testing
