Could you give me an example of one please? This is not something I have seen before so it would be interesting to check out.
I just posted a link to an image I found on a quick search on google on my previews reply #24, I don't have access to those type of app, but the button line is that it is very possible, it is actually not hard to do, so you don't really need a season hacker to do it and it is something that it should be more well known (IMO).
