v2.0.0

Initial release of version 2.0.0. Should be compatible with Mac OS X Catalina, Mojave, and maybe a few older releases. Your feeback is welcome!

Note: this release is not notarized with Apple. To open, right-click (or control-click) on the app and choose 'Open'. You'll see the following dialog. Click the Open button. You'll only have to do this once. (I'll figure out the notarization process soon so this warning won't appear in future releases.)
