First time user this season, and so far I am liking the site!
My concern is about the trade evaluator. It allows you to customize the typical lineups of the league (We are in a 1QB and 1OP(superflex) slot... which most people run QBs in), however it doesnt seem to account for PPR or 0.5PPR... Am I overlooking some way to configure the ppr settings for the evaluator?
If PPR / 0.5PPR is not an option for the evaluator, is there a good place for me to request it? I feel like it makes a huge difference when comparing RB values to WRs.
Thanks for you time.

Glad to have you!
I don't think you've overlooked anything. The PPR effect is large on WR's vs. RB's. but the trade evaluation tool is meant to give an idea of value overall, which should make it still useful. You're OP slot affects it too, since you can start more than one QB. What I would do is set the positions in a manner that emphasizes those positions a little higher. Try putting the QB's at 1.7, the RB's at 2, and the WR's at 3.3, leaving the TE's at 1. That should give you a little bit more of an idea on the value in a PPR with a OP flex.
