when I unarchive ScanCode-Workbench-macos-x86_64-4.0.0.tar.gz it gives me an application named ScanCode Workbench.app which is not the same as the older one I have which is named ScanCode-Workbench.app and I am not sure if that was intentional or not, but I think it might be better to stay with the same filename for the app.

This is also the case for Linux where it was ScanCode-Workbench earlier but now it's ScanCode Workbench
