You're welcome, Wade.
I tried to get an image of my finished drawing
from the Journal but the only option was to
resume Colors!. Then when it resumed it seemed
to hang. I then clicked on Play and dragged
the slider to 100 and the image finally appeared.
Trying to reproduce the problem, I noticed that
if I move the stylus pointer while the program
was resuming, it looked like progress started to
be made or at least updates to the display.
When I tried Play in with my current drawing
made via wacom tablet, the animation never
did complete. I don't know if the problem
was me not waiting long enough or what....
How can one get an image of the drawing for

I don't know if all wacom tablets have the same linear
resolution. Ideally, the value for "Suppress" would be
calculated from the native tablet resolution and the
drawing area pixel dimensions. e.g. a tablet with only
1000lpi resolution might work better with a value of 25.

Maybe whiten the image slightly as if looking through
paper and make it easier to have it be a visual guide
independent of the drawing itself?

You might keep track of the zoom center for each
level and then just pop the stack. The problem
I had would not have occurred if the zoom in and
zoom out operations were inverses.
The 'Center image' toolbar button is great, too.

I think the buttons look like mouse-ish events. At any
rate they can be detected and acted upon.

Looking forward to it.
