By default, every link in Horse Browser branches off into a new page on the Trail. That's great for research and most regular browsing. It's slightly worse for sites that are basically applications (Twitter, Instagram, Gmail) where the "links" are really internal navigation and you don't want a new page each time.
Two ways to handle it: open one link in the current Trail, or always exclude a site.
Open one link in the current Trail
For one-off use, toggle the link behaviour for the current Trail.
Mouse users: Menu > Navigation > Open Links in Current Trail
Keyboard users: ⌘ Y (Mac) / Ctrl + Y (Win/Linux)
Always exclude a site or web app
In Settings, add the domain to the Link Behaviour Exclusions list. The list ships with a few popular ones already filled in; remove or add as you like.
Mouse users: Horse > Settings
Keyboard users: ⌘ + , (Mac) / Ctrl + , (Win/Linux)
Add the domain (e.g. linkedin.com or *.linkedin.com).
