I plan on speedrunning this game since I've already beaten it, but that's not the point here.

Will there be a No Traces tab in the future?

I Agree. No Traces should definitely have a tab of its own.

Edit: The thing is though, not every mission has a No Traces Bonus. But I believe there is enough missions for it.

If people do runs of it, I will happily add it as a category

I'll do a run of it later if I don't mess it up, I already memorized it. Unless, of course, you're referring to other people.
