I plan to support this.

One comment:

Googling for "Steem Wallet" currently returns a lot of confusion as to what a wallet actually is on Steem. This is probably due to a combination of reasons such as out-dated development, lack of advertising/SEO, no product website, and complexity of Steem.

I know this isn't primarily a marketing proposal, but still it would be nice to see some effort planned to get this improved, so that the work on Vessel is of benefit to people looking for a Steem wallet and not just insiders who already know about it.
