+Tabs now open immediately with generated names; rename them only when useful.
+New spaces already skip naming, and new panes inherit the current directory by

+Direct resizing, previous/next agent navigation, last-pane switching, copy mode,
+and Neovim scrollback access avoid extra navigation or mode-entry steps.
+No documented native setting or CLI action opens Goto directly in search mode;
+that limitation remains under the configuration-only constraint. No input macros,
+plugins, or package patches are added.

+After activating Nix, reload Herdr with Ctrl+B then Shift+R; subsequent reloads
+can use Ctrl+Alt+Shift+R. The expanded shortcuts require interactive verification
+through Kitty, including popup working directory, pane swapping/resizing, and
+scrollback opening. The earlier bindings were reported working by the user.
+Verification (2026-09-10): formatting, flake evaluation, Polaris and Zenith no-link
+system builds, and whitespace checks passed. Both hosts generate identical Herdr
+TOML, accepted by installed Herdr 0.9.0's `config check`. No activation or live
+Herdr session changes were performed.
+The earlier activation installed the Herdr config and preserved `config.toml.bak`,
+but Home Manager later timed out (below).
 
 Activation fix (2026-09-09): Home Manager's service switch stopped and restarted
 the running SharePoint oneshot, then waited until Home Manager's five-minute start
