It would be great if there was a command provided to toggle the execution of the plugin at runtime. Something like :ToggleDiagnostics.
Sometimes, especially during reshuffling code the amount of diagnostics can be quite overwhelming and easy toggle for either the total plugin or at least the virtualtext (g:diagnostic_enable_virtual_text does not have an effect when changed at runtime [as expected]).
I just wanted to throw this out there in case someone else also finds this useful 🙂
