Hello @DevDudeDD, thanks for your kind words!
I totally see your point(s) :) . For example I also get frustrated when I accidentally select something by mistake, so an 'undo' button would be really cool, indeed.
At the moment I have lots of ideas for user control, such as selecting the types of functions that are used by the network, the color - encoding at its output (RGB / HSV / XYZ / LAB etc) and many more, but I am not sure if / when I will find the time to put them together in a well - organized application with a good UI.
As a first step towards that diretion I am planning to include a settings file, where the user may edit some of these options (such as resolution, functions, output etc) so if you are interested stay in touch!
