I would appreciate comment from @dantheman on this, but I don't think it will block that. Note that when you first change keys, Steemit.com will warn you that someone might have hacked your account because your keys changed. Just ignore that, since you did it yourself.
I do not change the recovery account, so I see no reason Steemit.com's recovery service would no longer work.
Would you mind adding that (recovery account change)? It would fit well within your app imo.
Ideally I would add support for the full recovery process -- setting the recoverer, requesting recovery and rejecting/fulfilling recovery. That's not a small change, but it's the kind of thing I'd like to support eventually. :)
You are the man! Well aside from @dantheman....
Thanks for your response... i would feel safe using this and changing my own keys if they will verify that for us. I think this is a breakthrough app for the security of my keys. Thank you for your time you put into this app.
