white-list option to exclude web sites from web browser history ceaning

hi,

I want to make a suggestion for the CCleaner.

I believe that it would be useful if there was an option to add, in a web site white list, the pages/domains that one wants to exclude from the web browser history cleaning.

This is important, especially for the web forum users, because every topic/post that you open is getting marked as visited by changing the color of the link and makes it easier to track down the new posts of a web board.

Currently, I do the web history cleaning of my firefox manually, but I hope to see this feature in one of the future versions of the CCleaner.

Sort of sounds like an extension to the Cookies to Keep, and it's a unique suggestion.
