@steem-plus would be one to add to your list, the app works great on Steemit and Busy.org, and you get many steem- plus points for different operations you do. Once you have points you will have upvotes according to your stake. This app is always evolving and points will be used for other things to be announced soon.
@stoodkev is always working on making it more robust and adding new features all the time! I rate this a 10!
Thanks for the suggestion @fbnfl4sun!
I'll look into @steem-plus more and take it in consideration.
