Definitely a big need for this plug-in! Thanks for developing it.
At first I didn't think it worked because in the General tab of Yoast the "Content" didn't turn to a Green "Yes". Yet, when I switched over to Page Analysis I saw the correct info. As long as the Page has the green light is what's important to my client.
Most likely I'm going to purchase, but can we expect periodic updates to improve little things such as the scenario stated above?
