Click to add for whitelist

[pritianka-zz]

If I am using the extension with whitelist, it would be nice to be able to add or remove a site from the list by just clicking on the icon and getting an option to do so. The use case I suggest this for is - If I am working on researching some articles on techcrunch.com I want to track the time but when I start to browse the site for fun then I want to disable the tracking.

Just a suggestion for enhancement whenever you guys have time; nothing urgent :-)
