Is there anything that TT offers or recommends that works like order flow?

You can use: VAP, MdTrader, volume delta, TTCDV. By cons there is no footprint what I find damage.

A new price array block or a Footprint feature in the yet to make an appearance "Analytical Block" would be a feature so many traders I know would make the switch to TT for.

I agree with you. The Footprint feature would really be an adva to TT. And let's not forget an improvement of Price Distribution (sessions, split period ...). Thank you.
