Application Homepage: Chapters

[krfdoc]

Describe the feature you'd like

Under "Settings"-->"Customization"-->"Application Homepage" I'd like an option to use "Specific Chapters".

So instead of just "specific page", what about "specific chapter"? ...or even "specific book"?

Describe the benefits this would bring to existing BookStack users

I can start on my most frequently used subject matter, which happens to be organized into a chapter

Can the goal of this request already be achieved via other means?

I could move all those pages to a book, but I feel that would just expand the overall tree structure. Additionally; even if I added that content as a book, the default "book application hompage" would list every book. Again; I'm just interested in narrowing the focus of the application homepage

I could also create a "table of contents" page and start with that, basically a link page to directly list to my specific pages in a chapter. But that seems redundant

Have you searched for an existing open/closed issue?

Additional context

I just want to say that you have done and AMAZING job developing this software. Your vision of simplicity and "stableness" is so perfect. I apologize if I missed a work-around or another feature request. This request by no means insinuates that I'm in ANY way disappointed in your application. Keep up the great work and the community LOVES it! Also; glad you're producing videos too!
