Icons form the Material Design Icons

[bernhard-kleine]

I have used the mdi-folder icon saying folder in the group edit window. With

mdi-shape-circle-plus this does seem to work using shape-circle-plus.
What is wrong?

Some of the icons on the material design website are not present in the font that we use in JabRef (which is essentially an older version of the Material Design Icons). Here is a list of all the available icons:

Can you please advise how to make that showing the graphics?
