Password reset flow is unintuitive

[richvdh]

Basically, I find it confusing that clicking the verification link in the email doesn't actually do the reset: you have to make sure you go back to the original client to do the deed. What if you lose the tab before the email turns up, or you just forget and try to go straight back to your mobile client?
