Fantastic plugin. One issue I am having trouble with is editing the featured imaged when it is a thumbnail.
With my theme the featured image is posted as a thumbnail on the right side of the text.
Hovering the image starts an 'edit' session for changing the featured image, but as soon as the mouse is moved over the text area, the edit session switches to a 'text' edit session.
The only work around I have to date, is to move the thumbnail to the left and remove left margin ( as even a smallish margin causes the text switch-out)
A solution like a short delay between closing the image edit left tab and opening the text edit tab would help. Or perhaps and option to switch tab sides.
Hopefully you can understand my issue. fixing this will be a major usability boost.
