Downloads/. - Optional battery optimizations prompt for long‑running generator tasks.
- Paste a supported URL in the top bar, or tap the bottom square button (Clipboard mode) to paste-and-fetch from your clipboard.
- Tap the bottom Download icon to process and show media. Use the per‑item actions to download.

Found under the gear icon (or via navigation):
- Dark Theme: toggles the app’s dark mode.
- AMOLED Theme: pure black surfaces for OLED screens.
- Enabling AMOLED forces Dark = ON.
- Turning Dark OFF automatically turns AMOLED OFF.
- Card Tinting: applies accent tint to media/generator cards.
- Long‑press Download (bottom bar): Queues all available media for the current post/type in DownloadManager (handy batch action when the preview shows multiple items). You’ll see a toast with how many items were queued.

- Clipboard quick‑paste: When the square button shows Clipboard, tapping it pastes your clipboard text into the URL field and auto‑starts processing.
