handyCalc 0.40 is the first version for the 0.4x. It does not has much improvements, but you can see a new on screen keyboard, which saves runtime memory and more easily for you to operate. I hope you like it.
More improvements is under development and need more time to merge to the main project. And the performance will be optimized to reduce the startup time and improve the graph plot in the version 0.4x.
