Fair warning, possible wall of text incoming XD
Now, you make some great points. I'll answer point by point and then try to say whatever else I have to add.

1. I'm not sure if I like this, as it could end up being a kind of censorship and a way of hiding people who disagrees with you. Maybe it will be a nice feature but only if you can give a "heavy" reason, like being a spammer, or making offensive comments and the like.
2. This is kind of tied to 1, maybe it'd be cool for comments to have one day delay where you can either accept or reject them, but again, only being able to reject with good reasons.
3. Totally agree with this, as you can imagine. I'll go a step further and say it should be possible (and maybe it's not technically possible, I don't know enough about the tech behind steem to argue on that) to downvote anonymously. I've seen posts that have no value, no effort, and are getting votes because they have "friends" or "vote me and I'll vote you people". And I can't downvote them, because then I start a war I'm bound to lose.
4. Again, completely agree. I get that voting power is suposed to be, partly, a measure of a user's "value" in the community, but since it can be bought, it can create a huge imbalance in power and make "low power" users be basically worth nothing (not on the money level, where this is obvious, but also when determining if a post is interesting).
5. Again, I agree. I get the "spend money to win money mentality", but it feels stupid that bad content can get visibility if you put money, while good content gets buried if the creator is not willing to pay. If we want to have a strong community with quality content, the rewards you get should be based on the value the people gives to your contribution, and bots can get in the way of that.
6. Yes, the social aspect of steemit feels kind of barebones and lacking in many aspects, this being one of them. The answer to 8 is basically the same XD. Those are basic features for any social network.
7. I don't even work how delegations work ^^" But it makes sense to be able to control them from the profile.

Now, additional thoughts. I feel like anononymity is a big issue in a platform where people feel like you're "giving them money" or "stealing from their winnings" based on what you vote. I think the core problem here is people and not the platform, but this is another topic that could feel a really long post. Given that fixing people is impossible, the platform should have tools to hide who votes you, to avoid revenge, vote me and I vote you, and other nonsense based on the fact that "woo, I can get money from posts".
I'm going to try to give some core ideas because this is getting super long:

• Anonymous voting
• Private messages
• Hidden payout & rankings based on number of votes. By hidden payout I mean we should see only the "X votes" on the post, not the expected payout. The payout gets resolved same as it is now, and THEN you can see how much money it generated.
• Some sort of limitation or flat-out removal of profits generated from self-voting. I know this sounds harsh, and also that I'm "poor" so it makes sense I will say this, but anyways. Right now someone with high power (the so called whales) can post whatever (like, literally a post with the word whatever if they want) and get a ton of steem out of it, just because of the self-vote. This of course will still leave us open to people voting each other to exploit the system, but it will be a first step in limiting this.
• Limitation or removal of bidding bots. Being able to buy votes (and therefore rewards) seems just wrong. You're investing to get a return, I get it, but by doing that you're removing from the pool of rewards that people can get for getting "legitimate" upvotes.

I'm going to stop here because it's getting late and I need to eat XD. I hope my proposals are useful, even if you disagree, just to start a debate.

Also, I think this way of communication is far from ideal, if we want to have some serious discussion maybe we should find some discord/forum/something else.
