[Concrete]

Really appreciate this feedback. I actually agree with you on the account requirement (I hate making accounts too, and then I went and created an app that requires one; the irony isn't lost on me!). But I'm a bit paranoid about server costs. Once we're certain that scaling this in AWS is going to be as cost effective as we think (and it's looking pretty good), I'll feel more comfortable removing the friction of having folks make accounts. My real expertise is finance, so I'm outsourcing much of the tech stuff, and I'm leaning heavily on my team for their input in these areas.

As for having to log back in immediately after exiting the app (and not saving assumptions)--that's a real pain. I'll have my guys get that fixed ASAP.
