Build a tmux status bar by looking at it — reorder segments, switch powerline separators, set pane borders and the prefix key — then copy a complete .tmux.conf for tmux 3.0 and up.
A live terminal preview redraws as you edit. Powerline separators are drawn as CSS shapes, so you don't need a Nerd Font to see them.
The exported config covers the status bar, panes, messages, and key bindings, using the real U+E0B0 glyphs.
It all happens in this tab: no account, no upload, no analytics.
