SNL: Annotation Improvements

This issue was created automatically from an original Mantis Issue. Further discussion may take place here.

It would be nice to be able to select font size and hide annotations and labels. For example the node numbers displayed by pick can cover most of the neighboring cells for high resolution displays and closely spaced nodes. If the user could change size or hide this display, they could see to pick adjacent nodes.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
