+
+It's off by defaut, but if you set `hide_inactive_cursorline = true`, then this plugin will hide the cursorline for inactive windows so the mode highlight will only be shown in the currently active window:

+
+Note: if you're lazy loading this plugin and want to hide inactive window cursorlines, make sure `event` is either set to `VeryLazy` or as follows:
+
+```lua
+return {
+  'sethen/line-number-change-mode.nvim',
+  event = { 'ModeChanged', 'WinEnter', 'WinLeave' },
+...
+}
+```
