This describes exactly why I choose console demos in the first place.

This is just what I like about the console, too. I often use it to sketch up
new concepts without adding controls and click buttons during testing. Then I
slowly move code out of the main *.dpr into separate units as much as possible.
As things mature, I start coding the GUI, based on the separate units. In the
end, both the GUI and the console share the same separate unts. DISQLite3 is
good in this sense as it works well with both GUI and console applications.
Back to the demos, however. Thinking it over, I realize that good demos pick
people up at familiar places and guide them along unknown paths safely. I
assumed that the console is such a familiar place. While this is true for some,
I am learning that the GUI is more familiar to others.
Over time, I will go through the demos again to simplify the code, add more
comments where appropriate, and more GUI as well.

Will do. If you have some ideas or code semi-ready, I would be glad ifi you
would share it and I could extend it for you.
