v17

This can be seen as advanced todo lists PDF.
It supports a type of todo items that need further decomposition because every item has 12 pages inside.
Also it supports catchall for relevant ideas/inputs that can be processed later.
Adding titles and marking used links is a good idea to navigate within the PDF.

First page (root) is a table of contents:

• First row of links goes to 12 ideas/inputs pages.
• Then two rows link to 12 lists pages, these links are bigger so there is space to give them name when needed.
• Other links below link to items of lists in case that is needed at some point

Lists:

• Lists can be accessed just by turning to the next page from the root
• Every list has 7 items, linked by squares at the left

Items:

• Items have 12 consecutive pages each
• Also all pages have links to ideas/inputs pages (in the upper-right corner)

Ideas:

• linked from every page to be very accessible for addition
• Overall 12 pages with navigation between them at the top or by turning pages

Also title can be rendered on every page by setting title: 'ABC' in Lists.rb.
It should be useful if separate PDF file is used per project.
