Trails are the one thing in Horse Browser that takes a minute to get used to. Once they click, the rest of the browser stops feeling weird. Everything below is the short version of what you need to know on day one.
What a Trail is

A Trail is the path your browsing takes, drawn out in the sidebar. Click a link and the new page branches off the page you came from, instead of replacing it. Click another link and that branches too. Nothing disappears. Horse merges what tabs, history, and bookmarks each tried to do, and shows them in one vertical layout.
Two shapes you can make:
- Sub-Trail. Created automatically when you open a link from inside a Trail. Sits underneath its parent, which is how the hierarchy gets built.
- Side-Trail. Branches sideways instead of downward. Useful when you want to chase something tangentially related without burying the thread you're already on.
