Suggestion: Steemit 4 notification proposals

Hi, I have been on SteeMit for 5 days, but I realized that a few things are missing...
I will try to explain in turn

1. Subject message notification
For example, if a follower sends a message to the article we share, we can not see it because we do not receive a notification.
As an example, we can look at facebook and YouTube
If we share a post on Facebook and there is a comment under it, it will come to us notification.

Sample 1;

Sample 2 ;

2. Answer notice

The other thing I noticed is that, for example, a message was sent and answered, but unfortunately we do not receive a notification.
As a repeat example, we can look at facebook and YouTube

Sample;

3. Topic sharing notification

We follow people at Steemit
We follow people at Steemit, but unfortunately we do not get a notification from people we follow when they share a topic
I follow @ haejin as an example, @haejin share an article, but that does not come as a notification to me.
We can look at YouTube for the best example of this

Sample;

Solution;

We can put a notification bar for the solution, and any update can get message to this notification bar

Sample;

for example, such a system can be made, so we can be familiar with everything :)

Google translate + my bad english knowledge :)

In addition

4. Notification of mention

For example, if you tagged a person by typing @shankstaicho in a conversation or in a message, you might be notified that someone mentioned you
