Install From Anywhere
- Local file picker: Auto-scan storage, browse packages, or full file browser modes.
- Remote download: Paste a URL; the package lands in Download/UniversalInstaller/ with its real filename.
- Download history: Re-install, copy source URLs, and manage files without digging through folders.
- App integration: Open APKs from Chrome, Gmail, or Telegram even when URLs lack extensions.

Preview Before Installing
See app name, icon, version, package, size, SDK targets, CPU architectures, languages, permissions, split count, and OBB count — all before you commit.

OBB Support
- Bundled OBBs inside XAPK/APKM are detected and copied automatically to Android/obb/.
- Manual Attachment: Attach standalone .obb files to any APK via the preview sheet.
- Foreground Worker: Keeps copying even if you leave the app, with progress notifications.
- Smart fallback: Uses direct I/O, Shizuku, or SAF (per-package folder grant) as needed.

Root & Shizuku Power User Features
- Targeted User Installs: Install apps to specific profiles (Work, Island, etc.) or all users at once.
- Silent Operations: Install or uninstall without system confirmation prompts.
- Advanced flags: Replace existing, allow downgrade, grant all permissions, bypass low target SDK blocks.
