It's been 2 weeks since 
In the week following the post, we have worked hard to add the new features promised in the beta launch. In fact:
We’re now on the WordPress Plugin-store!
SteemPress V1.0 can now be found in the plugin store on WordPress!
https://wordpress.org/plugins/steempress/
New features in V1.0 includes:
Option to auto-upvote your post
Option to set rewards as either 100% STEEM Power or 50/50 split SP/SBD
Option to add a link to the original WordPress article at the bottom of the post made on STEEM
Ability to choose up to 5 tags to be used on STEEM from the WordPress menu
A connection and username/posting key tester on the settings page so you can see if something is wrong with the server or your configuration that prohibits posting
Beneficiaries rewards
Like most other apps on STEEM, including esteem, dtube, dsound, dmania, utopian and zappl to name a few, we intend to use benefactor rewards to help run SteemPress. The benefactor rewards is currently set to 10%. In comparison, Dtube and Utopian both take 25% benefactor rewards while Zappl takes 15%.
It is worth noting that the benefactor(s) only receive a part of the Steem Power reward from the post, leaving the SBD rewards untouched. Assuming the post is set as 50/50 split SBD/SP and that 25% of the total rewards go to the curators, the 10% benefactor rewards only affects 37.5% of the total rewards. With SBDs also trading above its peg, the percentage of the USD rewards is also significantly lower.
Howo and I are determined to do our best to keep this percentage low in order to incentivise more use. Discussions on the use of benefactor rewards, what rates they should be, or how we can make it more attractive to use SteemPress are of course welcomed in the comments.
Final notes
Again, I would like to thank everyone who contributes to the project with ideas, suggestions, feedback and support! A special thanks to our most active early testers: 
And for all the rest, I look forward to reading your comments!
Take care and SteemPress on!
