Thanks, it's a good idea to only put the version number where people would look for it and not have it show up constantly in the POS window.
I've been using SambaPOS for over a month now, and really never saw the version number in the login screen. Even when you told me about it, I had to look twice to see it. I think white font on that grey background is a bad choice. Maybe try to make the font embossed, or with slightly thicker edges in future versions to make it stand out. Just a suggestion.
Thanks.
