Feature request to use clickable header

Is your feature request related to a problem? Please describe. I had been working with the previous version of Jupyterbook that allowed the following feature that has been removed in the beta version:

• The header names could be linked to an overview file so that if you click on the header, it takes you to a landing page (see example here). This in a beta version appears as a non-linkable text header, which required me to create an extra link for overview files (aesthetically and intuitively, the previous version for this was more useful) - see image below.

Describe the solution you’d like

• Can the hyperlinking header with a landing/overview page of the section like in the previous version be used in the current version?
• It is minor, but similarly is there an alternative for divider: true option for the TOC file in the beta version.

Describe alternatives you’ve considered

• Naming my file differently so it doesn’t appear as repeated text (Screenshot below)
• Adding my landing page to sections which without any warning removes the entire section of the book

Additional context

Feature request based on the following view:

• Previous version

@malvikasharan one thing that we could try is to add some custom CSS rules that make the top-level pages look like headers, and that way you could style it however you like.

E.g., you could use a CSS rule like this to make the top-level links really big:

nav.bd-links ul.sidenav_l1 > li {
    font-size: 1.5em;
}

Thanks Chris. I was using header only for differentiating sections from chapters. But based on this discussion, I suppose I will drop that and just go with the title option. Thanks for taking the time to respond to this issue.
