New Features
Create a floating pane above the tiled layout; unlike popups it is not modal and behaves like a regular pane (bound to * by default)
Show line numbers in copy mode — default, absolute, relative or hybrid — styled with copy-mode-line-number-style and copy-mode-current-line-number-style
Draw messages and prompts as a single format that can overlay part of the status line (message-style needs "fill" to cover the whole width)
Automatically make the pane under the mouse pointer the active pane
Customize the preview indicator in tree mode (with tree-mode-preview-style)
When enabled, clipboard requests from a pane are forwarded to the outside terminal
New copy-mode commands: scroll-to-mouse, recentre-top-bottom, and scroll-exit-on/off/toggle
Breaking Changes
- !message-style now needs "fill" to cover the whole status line width (the default includes "fill=yellow")
