JUst Write not working as expected and lots of questions about Just Write

I was using a complex, highly customizable theme a while ago before I found Just Write yesterday. I love the big font and the clean theme, but have a lot of questions, which I hope you can reply and give solutions to:

1. How to remove the dates from blog posts?

2. How to make the top menu sticky?

3. The Main Sidebar widget area option isn’t there in the customizer / theme options, how to bring that option back? I tried installing this time on another (test) blog and it shows the Main Sidebar option fine. What could be the problem?

4. How to add a header image at the top instead of just a logo?

5. The four styles included in the content option seem to change nothing when changed to. What are they for?

6. How to have widgets display H1-H6 header text? Including the H1-H6 tags has no effect on the text.

7. Clicking the BROWSE link in the top menu just adds a # to the end of the address-bar and stays on the page. Doesn’t do anything else. Same thing with the search. Both these work on my other, test blog, which has almost no posts.

8. What’s the space between the BROWSE and the search button for?

9. I wish to include links in the footer. Any HTML doesn’t show up, only the text shows. Also, how can I have 3-4 boxes or widgets in the footer? I had this functionality in the previous theme I used.

10. How can I increase the font size used for the widget titles? It’s too small.
