Fonticons like tag plugin...

Hello to everybody at support.

I have now a question about FontIcons. In this cas I don´t want to add new classes like in my recent post about xtypo.
But I need to be able (if possible) to insert in another places.

For example. I am using zentools from JoomlaBamboo and (by suggetion of then) in the Read more text instead of only a string I could insert a tag (and a string).

I want to now if its possible to do the same with FontIcons (like the button only appear in the editor).

I attach screenshot that how to get a +info (and the plus its a font icon) to easy things for you. The access data its the same that I wrote in my recent post.

Thanks and hope to hear from you.

Best Regards.

Thomas C.
