I hope this is in the right place and I'm not creating a duplicate thread, but I've been getting a tad annoyed with navigating through books when using D&D Beyond's Compendium. Browser, not mobile. 

I'll use Lost Mine of Phandelver as an example.

You click onto the book and you're taken to the list of content. This adventure has an Introduction, four Parts, two Appendices and Credits. Each of these has its own division of sections within.

I click into Part 1: Goblin Arrows, and I have the entirety of Part 1 on my screen to scroll through. For ease of use, I see a floating navigation that allows me to click onto any of the sections within Part 1 and jump to that area.

What bothers me is that is the floating navigation's limit. When I'm ready to move onto Part 2, or maybe head to one of the Appendices, I have to either hit the Back button, scroll back to the top (or click Back to Top in the navigator) and click Back to Lost Mine of Phandelver. Back onto the list of content, I can select what I next want to check.

That's really not a lot, which is why it's only a small annoyance and this isn't much of a complaint. I've been opening into new tabs so that I always have the list of content open. It'd just be nice if that floating navigation was more useful, like the quick mock-up I did below. Ignore the double Appendix B, I meant to replace that with Credits.

Alternatively, if this isn't possible for any reason, it'd be really nice if there were links to the previous and next sections at the beginning and end of the web page.

For example, if I'm at the end of Part 1: Goblin Arrows, there will be a link to continue on to Part 2: Phandalin.

Roll for persuasion! 10
