@Scott: Great work that you implemented CKEditor 4.3 into 1.7 dev, superb!
One issue for users and developers to solve:
1. I tried the editor and wanted to change the tons of buttons to only 5 chosen buttons
2. I was searching around, tried to edit the config.js etc.
3. After a while I found out that I need to edit the file qa-wysiwyg-editor.php
When updating q2a - the changes will be lost. Plus as you see, I had problems finding the correct place of the config.
My advice: Add a qa_opt() field and save all the ckeditor toolbar config there. Then the users can easily edit the toolbar from admin/plugins.
