Widget support please? [Request]

This is an excellent plugin, and works perfectly – in pages.
However, it crashes if added to a widget (unrecoverable block error). =(

Additional feature requests:
1) It would be nice if there were standard wordpress reset and/or “reset to default” options for all of the settings.

2) The ability to add a border around the icon would also be great.
I was almost able to do this with css on the svg element using:

{
border: 2px solid #074b7e;
border-radius: 200%;
}

… but there are some padding issues that I haven’t figured out yet. A square icon gets cropped if I use a circle border. Perhaps the svg just needs another container?
