moerl, don't get too distressed over what seems like abandonment by a developer. While it's not a good sign with ever-changing software, such as internet apps, it's not uncommon for a utility app like a calculator, registry cleaner, conversion software, image resizer, and so on will be built and then left alone at a stable version. In Moffsoft's case, they've done everything they intend to do with it. My absolute favorite was
QuickCalc, which was abandoned soon after it was released. QuickCalc calculated as you typed, so that you can see your result as it was typed without even having to hit the Enter key. It has the bad habit of not remembering its last position, but no one has been able to replicate its sheer ease of use.
