I checked mptrack.exe ( v.48 ) with it and noticed at 'Icon group 200' the same bitmap as 'Icon group 201'. Quite silly.
So a fine opportunity to replace the second one with another icon. Because adding things is often more complicated.
Before this, I used an external 32x32 ico-file, I made from the splashscreen, to indicate it being the latest beta-version.
I managed to insert this ico-file with reshacker, instead of the 2nd duplicate, providing a 2nd choice of program-icon.
A first experiment, while playing safe, because the executable stays at the same file size.
Adding more Icon groups is another step.
The version of beta .48 with this tweak :
