There are literally hundreds of features. Here are only very few of them:
- Making you king over your desktop - You have a beautiful wallpaper on your desktop and you want to admire it in all its glory? Your wallpaper is probably hidden behind the open windows, the icons and the taskbar. BioniX Wallpaper Changer can temporary hide the icons, the taskbar and minimize all applications.
- No installation required - Don't you hate mammoth programs that install literally hundreds of MB of crapware in your system? Our software doesn't install stuff in your system. To uninstall it, just delete it!
- Portable - You can move the program around in your computer without reinstall. You can put it on a USB stick and take it with you or you can send it via email.
- BioniX, the navigator - Two handy buttons allows you to navigate to the next/previous wallpaper. You have a global (system-wide) shortcut for these function, so, if a wallpaper that you don't like accidentally lands on your desktop you can advance to the next/previous wallpaper without opening BioniX Desktop Changer. It can also play a user defined sound file every time it changes the background.
- Flexible time control - You can set the interval at which your desktop wallpaper will be changed. The program is extremely flexible allowing you to choose any interval between one second and 60 hours in increments of one second, one minute or one hour.
- Low hardware requirements - BioniX needs only 4-5MB or RAM to run so it can work even on ancient computers.
- Advanced Playlist Editor with wallpaper rating system that supports up to 500,000 background wallpapers.
- Dual monitor support, smart enlarge, smart desktop background color, smart tile, smart borders, mirror effect.
- Stores your background wallpapers in multiple thematic playlists.
- Intuitive graphic user interface - Even if BioniX Desktop Wallpaper Changer is the most complex wallpaper manager around, we kept the main interface simple and uncluttered. - If this is too much for you to digest, you can switch to the Minimalistic Interface which was even more simplified.
- Supports WB1 file format.
