I'm currently working on adding secure search support to the next release of Googlebar Lite. This new feature complicates things slightly when using a non-default, top-level domain (google.co.uk, for example). Google's encrypted search feature is not available for all search types, and is currently only available via one domain: encrypted.google.com. As such, here is how the new option in Googlebar Lite will work when enabled:

• For search types that support encrypted search, all queries will be sent to the encrypted domain. Your custom top-level domain (if you have one selected) will be ignored.
• For search types that do not support encrypted search, all queries will be sent to the top-level domain of your choice.

I want to make this option's behavior as clear as possible before I release the extension, which I hope to get around to doing in the next week or two.
