Maybe my approach to talent crafting is wrong, but it would be helpfull if I could draw a path in the cards. So when I'm building something from the lower rows in several days, I don't have to remember what I was doing at every step. I was building patience rare for Doldren, don't judge me, and i end up with a different expensive card I can't even use to craft patience. Having drawn what i was doing before would have helped.
Also I think that the current crafting system would benefit a lot from a companion app like warframe, even if maybe is not fisable.
