Works great! Is it possible to create an update for sms messages?

I like this app. Cool that the app icon is hidden so to speak. I was wondering is it possible to create the same app or update so that the sms messages or calls are not shown in the regular apple messages or phone folders ( the green default icons)? Basically what it would be is its own sms feature within the app, totally independant from the regular contacts. Basically, I would have to go into the bbcalc app in order to see my missed calls or sms fom the hidden contacts? If that is posssible? I give you guys 10 Stars!!!;) Thx
