 ## [Unreleased]
 
 ### Fixed
+- Pre-update backup on the **Joomla Update** page is now **seamless** (Akeeba-style): after the full-screen backup runs, the plugin auto-ticks Joomla's "I have taken a backup" checkbox and clicks Install, so the update continues automatically instead of stopping for a second manual click.
 - Pre-update full-screen backup now actually fires on the **Joomla Update** page. The "Install the update" button posts to `option=com_joomlaupdate&layout=update` (Joomla's confirm/updating page) — carrying **only `layout=update`**, no `view`/`task` — so the previous match on `view=update`/`update.install` never triggered. The plugin now intercepts `layout=update` (as well as `view=update` and the legacy `update.install`) and returns the browser there flagged `is_backed_up=1`.
