STEEMIT User Interface/Experience improvement suggestions

This is such a great site. I have been posting and reading other people's posts actively. But there are a few things that can be done to improve the user experience. I will list a few that I have comes across:

• There should be a search box for tags on the sidebar where you have a list of tags

      When the user enters a keyword in the text box, 
      a text based search should be done for tags and 
      the tags related to the and brought to the top so the 
      user does not have to go to the next page to search for the 
      tags he/she wants.
  

• When you create a story, it will be great to know what tags are available so you won't have to go to the sidebar and look for the tag you want.

      The solution I suggest is when the user clicks on the 
      tags input field,  a box should appear at the bottom containing 
      all the  vailable tags and if the user  decides to select one, 
      on click the tag should be added to the Tags text field.
  

• Story text editor should have the options for bolding/highlighting/linking etc (just the things we see on standard text editors). Here is an example:

I will post more as I come across things that need fixing. My apologies if the above things have already been implemented.
