BigSmileys and new custom smiley event

I've made some changes to that plugin (compiz/beryl bugfix, and some other little things), and there's only one trouble remaining: when you add a new smiley, I don't know how to realize, and so my menu stays unchanged and produce bad effects (smileys events bind to other smileys, the new smileys appears in any category if you use them)... So I think it would be good to have an event when you add a custom smiley so I get the new smiley name as a parameter, ask for the category and update the menu. Is it ok?
