Does cTrader_Theme Studio hold up under prop-firm restrictions?

Alright, straight to the point—I'm skeptical about this cTrader_Theme Studio. It's free, yes, and seems geared around Doji patterns, but I can't shake off the feeling it might be just another shiny distraction. My real question is: has anyone here tested it under prop-firm environments? I don't need another tool that crumbles as soon as real-world restrictions kick in. Thoughts from those who've actually put it through the wringer? Spare me the flowers and rainbows—just need a yes or no if it actually delivers.
