I forgot to say that one of the fist thing I want to do is an installer, so
more people can get in touch with ZigGis (I am dead sure many many people
wanted to use it but didn't because they don't know c# and how to make it
working).
Whit more people installing ZigGis we can even get to know more bugs and fix
them (a sort of alfa-beta test)
