select icon set

Hello. Thanks for this useful module.
Actually I'm using it with tinymce inside the wysiwyg module on D7. I've uploaded some icon sets. Now they're all mixed together. I've thought that it would be nice to let the user chose which icon set to use in the popup window which opens by clicking on the button on the editor toolbar. I think this feature would improve the usability of the interface, because having hundreds of icons doesn't let the user focus well on one image or onother, imho.

Basically the user should be able to:
chose the iconset
insert the chosen smile
change the iconset
insert another smile
...post the node

What do you think?
