OpquastI have a free add-on for you BlueGriffon users : it's an automated accessibility checklist built by the wonderful Opquast people. I took their checklist, wrote the corresponding JS-based tests and turned the whole thing into an add-on. The add-on adds a new menu entry to the Tools menu. It works for the last focused document and it works for both Wysiswyg and Source views. Localized in english and french.

The add-on is available here. Please save it onto your hard disk and follow the installation instructions starting at step 3.
