Content Mode on Front-End

Imported From: http://groups.google.com/group/in-portal-dev/browse_thread/thread/bb0a7da2158943f0#

When we work with a team of translators/content reviewers, it'd be very useful to be able to have a "content mode" on front-end. This would be also very practical when you check all your pages, and need to change just a label somewhere.

I think about admin users who could have a special perm to see displaying these magic yellow boxes.

Additionally, what do you think about a system to make label translation as easy as displaying an input field when clicking the Edit button, without any pop-up/modal window?
