"MktEditable" class works in Landing page templates the same as email templates

I'm sure this has been mentioned a number of times, but it'd be really nice if the same functionality was adopted by landing page template design as email template design when class="mktEditable" is added to an element.

The reason being that I want to maintain the same format, positioning, etc across all landing pages. I know this is possible my noting dimensions, applying the same style in the rich text editor for each landing page, etc, but the solution used by the email template design (mktEditable) is MUCH more elegant.

PLEASE! Let's implement something like this! It's a great feature of email templates and something that's dearly missing from landing page template designs.
