I do not use these features though I did not remove them intentionally (I think you have to activate cheat mode for them to be available but I dont know how thats done either)
I think BB's pack has them tested (and more of these screenshot related features) he also was kind enough to adopt my modifications to his track implementation try using his with a version based on his game rather than pure MWM but I dont know you can try it on MWM it might work I skimmed through the script I didn't find anything standing out to be incompatible with MWM but I might be wrong.
