Add a "separator" option to group top links

[skal-dB]

One of the thing I love with this plugin is the way you can play with links displayed at the top of the screen.

I wanted a clear frontier between office stuff and entertainment, I can do that, and I can even add some emoji's (ow yeah!)

I don't feel like adding some emoji's feature would be a good thing, but maybe having a way to group links could be great.
It would help keeping something organised and neat.

Here is my trick for now (pipe + fake url), but maybe there's something better to do :-)
