@atomcollector, I know that from the user experience point of view that would make all the sense, but there are technical and security issues behind that kind of page:
1. Having such a page the user would need to input their active private key. That is the kind of responsibility I don't want to have in DSound. Since DSound never has access to your wallet, the only harm that can come from any security flaw in DSound is some spam posts or comments, but nothing more.
1. By supplying such a page, it would be a big incentive to have people forging that page for fishing sites as they already did for SteemConnect, so my idea is that people should be very careful where they use their private keys, specially the ones that allow access to their money like the active private key. 

To get an easier way of accessing and operating your Steem acounts, I suggest Vessel Wallet from @jesta (witness) as my favorite tool to handle all my account operations. It's free, open source and it is maintained by our highest ranked witness, which can supply extra peace of mind related to security... You should always be reluctant to input your active private key on any application that you don't know!
