 ## [Unreleased]
 
+### Added
+- `DeckTrigger.FloatingButton(icon = Icons.Default.Build)` sets the floating button's icon from an `ImageVector`; the composable `icon` slot is now documented too.
+- `DeckStyle(titleIcon = …)` replaces the bug icon next to the drawer title; `titleIcon = null` shows the title without an icon.
+
+### Changed
+- The SharedPreferences browser lists only the app's own files. Files written by libraries and the system (WebView, Firebase, Google Play services, AndroidX, DevDeck) are behind a *Show library files* switch.

 - The swipe is detected without taking touches, so taps, scrolls and system back keep working.
 - On an emulator, a mouse can't do a two-finger swipe: use Ctrl + Shift + D or the floating button.
 - If your app uses two-finger horizontal pans (maps, canvases), turn the swipe off.
+- To use your own icon on the floating button, pass an `ImageVector` or any composable:

+```kotlin
+trigger = DeckTrigger.FloatingButton(icon = Icons.Default.Build)
+trigger = DeckTrigger.FloatingButton(icon = { Icon(painterResource(R.drawable.ic_debug), contentDescription = "Open debug menu") })

 The drawer header shows the app version, plus chips for a new test build, an active recording (with a *Stop* button) and any network or memory simulation.

 `DeckStyle` also sets the panel width and colors; `collapsibleSections = false` shows every section open, and `oneSectionAtATime = true` closes the others when one opens.
 
+The icon next to the title is `titleIcon`: pass your own composable, or `null` to show the title without an icon. `Icon` picks up the tile's colour. The floating button's icon is set on the trigger (see [Opening the drawer](#opening-the-drawer)).
