Feature Request: Configure Error Handlers

[sjelin]

Pending angular/protractor#4052 & angular/protractor#3857 & angular/protractor#4053, Protractor would like to retry a command if the issue described in #32 is encountered.

This would be necessary for getting rid of Protractor's wrapping of selenium functions, though that may be impossible anyway since you'll never be able to do unwrap ElementFinders into WebDriverElements form Blocking Proxy. So maybe this feature request is misguided.
