Surround the Modonomicon with 8 pieces of paper to add 8 book marks to right side of the opened Modonomicon
Shapeless Gold nugget + Modonmicon 'favorite page' allows the player to always open to a specific page when enabled (such as the index)

Additional context
The favorite page given by the gold nugget should have a toggle option for the 'pin.'
Favorite page and book marks would be displayed by a gold nugget in a box and book and quill for the favorites.
Shift click the gold nugget to enable and set a golden page.
Click the gold nugget to toggle favorite page on and off. (brightens the box and nugget when on)

Describe the solution you'd like
The right sidebar of the page is very empty. This could be a great place to store bookmarks to specific entries. Maybe per-category, or just globally

Closing this in favour of #218 which works a bit differently but adds easily accessible bookmarks that are easier to implement
