Problems to read the documentation

Hello,

I am trying to learn Boost.Test from the documentation, and I am facing to two problems :

1. The main page doesn't show all the hierarchy's depth ; and when I select, for example, [Declaring and organizing tests](https://www.boost.org/doc/libs/1_85_0/libs/test/doc/html/boost_test/tests_organization.html), that doesn't show either all the sub-hierarchy (the content of **Operations on dataset** doesn't appear)

2. Because of CSS, the visited links have same color than not visited links.

Is is so very easy to feel lost , and as I can't read this big documentation in one go, to know where to resume my reading.
