Mod Organizer supports Oblivion. I see no reason to add the program to utilities as there are several advantages:
- Mods are kept completely isolated from each other -> no more messy data directory
- Profiles
- Drag&Drop load order AND installation order management
- full control over the priority of BSA files
- Nexus integration for easy download, installation and update of mods
- GUI support for manual installers
- partial compatibility with BAIN and fomod installers
- Savegame viewer
- active required mods from save game
- Archive Invalidation
- Categorize mods for better overview (customizable)
- easy overview of file conflicts
- complete help system
- Supports Oblivion, Fallout 3, Fallout NV and Skyrim
- no dependencies. Just unpack and go
- localization (currently: german, spanish, french and chinese)
- automatic self-updates
- BSA unpacking
