I don't mind at all, even contrary, I expect that you use it in your next Add-ons. I saw that you also had some troubles managing menu items i web interface. I spent several days in researching how all these javacripts, jquery, css and other thins interoperate and can say that ShareCenter's web interface more complicated than I expected (actually I think that there's overuse of javacripting but that's only my humble opinion). However, I have more suggestions for improving your work but we can discuss it over PMs.
