Undo and action previewing are definitely two things I want to add. My BF also pitched the idea of adding an "arcade mode"/"endless mode" where you can just play the card game. I have a short list of "quality of life" changes. And, the stuff you point out is definitely there.
Also, I definitely understand that frustration. Tho, I personally found watching the un-TF to be as equally interesting. I kinda want to tweak it so it's more gradual at lower TF stages.
