Post Description

Tabs, splits, and tmux work fine until you have several projects open with logs, tests, and long-running shells. I kept rebuilding context instead of resuming work. Horizon puts shells on an infinite canvas. You can arrange them into workspaces and reopen later with layout, scrollback, and history intact.

Built in 3 days with Claude/Codex, dogfooding the workflow as I went. Feedback and contributions welcome.
