The calculator was originally part of the examples repository but has since been moved out to its own repository. This is the first release as a separate project and includes an improved button layout, a new icon, upgraded Fyne to 2.0.3 and a few other code cleanups and improvements. The Fyne update notably brings improved mobile support, new button tap animations and compilation fixes on FreeBSD 13.
This release also features pre-built binaries for various platforms. Builds for the Apple App Store and Google Play Store will be available as soon as they are accepted.
