Rated 4 out of 5 stars
Excellent addon except when saving a new layout will only accept alpha, numeric, and the underline (_) characters. It will not accept a space or any other special characters except the underline. This makes for a sloppy-looking entry. Please allow it to at least accept the space and minus (-) characters.
To MaxStirner, you should be able to drag and drop any link into any tab. Maybe this will help in your Google problem.
Available in version 6.3
