Much thanks - I've been waiting for the feature for a very long time. It was a major impediment to the adoption of Google Docs for anyone working with contracts - lawyers, real estate agents, and government contractors.
I only have one other major hangup when it comes to converting people - I'm begging to be resolved - PAGE BACKGROUNDS. They like to make their proposals look pretty - like it's on letterhead or other frames. I've tried every workaround I can think of, it's impossible.
Oh, and tables - while they're pretty cumbersome, we can work around the limitations, but when the team decides to revise tables in documents, please consider adding a "text wrap" feature for them - exactly how text wrapping for images works.
Other than that - I think you're just about there. :) Nice job.
