Browse the internet with one simple sidebar that organises every page, task, and project inside 'Trails®' — nested groups of pages that capture the natural flow of each internet journey. That's right, – no more tabs, bookmarks, or history.
Vivaldi is my main browser, I use Horse as a research app. Currently, Horse is kind of a one-trick pony (sorry), but it performs its one trick really well. The "trails" concept works great for me, I love the interface, and it's just plain enjoyable to use.
