Other clean variants used an older core (2.02) and thus, K-Lite had some features that others didn't have. K-Lite included multiple search tabs, a custom toolbar, and autostart, a download accelerator, an optional splash screen, preview with option (to view files you are currently downloading), an IP blocker, Magnet links support, and ad blocking, although the clients based on the 2.02 core abstract these functions to third-party programs.
