I thought about it now... I think it can be a little hard for me to do this, maybe impossible... I don't know how to check which latest version in my drop box...
Creating new version, I already need to know what the number can be in the next version... I can't to know this. I decided about the version number when I started to packaging...
For example tweak will check you version, but can't to know what to download because I can't to know what the next version number :/

I think I will leave this like now, and start to learn how to create repo....
