Horse Browser has two ways to group Trails together: Folders and Areas. They look similar at first and people often ask which one to use. The short answer: Folders for related research, Areas for whole parts of life.
Folder vs Area
A Folder is a Trail that starts with a folder rather than a web page. Useful for grouping related Trails, say, every Trail you've opened while planning a trip, or every Trail about a single client.
An Area is a top-level container with its own header. Most people end up with one for work, one for personal stuff, and maybe a third for a side project. Each Area can hold Trails, Folders, and Notes.
Folders and Areas existed because early users kept asking for them after spending an afternoon in the sidebar. The shape of the request was always the same: "I have a lot of Trails on the same theme, I want them grouped."
