It's good your being vocal about these suggestions on Steemit, we need to speak up or these things will never get resolved. Hopefully the devs see this post. I think the most important one is number #5. If I didn't have SP, I likely would have quit in my first two months on here. Many of my friends have joined this platform thinking they will make money, and they post some great content, but don't receive many upvotes or comments other than my own. I agree with your fifth point but the money has to come from somewhere :/
