The built-in Application Monitors are very few and don't cover a variety of applications in an infrastructure. It would be great to create an Application Monitor that not only covers Performance Monitors (like in a device template) but covers processes, services and URLs. This would make onboarding new applications much faster then it currently is.
If I had an application farm with 10 servers that all leveraged the same processes, services, event logs, etc, I have to go to 10 individual servers and add those monitors instead of creating a single Application Monitor like exists for SQL, Exchange, AD, etc
