Simon 5 is coming soon!
Simon version 5 is currently in beta testing. It is a massive update, introducing a much-requested feature: syncing the Simon data between multiple Macs, plus a Simon Status service, a Link Checker filter, improved Find filter, iMessage and Speak Error notifiers, a new app icon, and much more.
Important: please note that Simon 5 requires a minimum of macOS 10.12 (Sierra), and will be a paid upgrade from Simon 4 after the beta. Purchasers since September 1, 2020 automatically get a version 5 license (that also works in previous versions).
Re: Delete Failed tests?
Sometimes failures are very brief, so Simon can't access the server, but checking yourself a little later works. That still indicates a problem, though.
There currently isn't a way to remove log entries (and adjust the stats). I'm not sure that'd be a good idea, though I'd consider it if enough people asked for it.
Re: Delete Failed tests?
Still a good idea to remove failed tests due to Simon's connectivity issues while the server is running fine.
