Request for feature: Show [NotNull] and [CanBeNull] annotations in intellisense-box

Check out Agent Johnson:

Thanks for pointing me to the Agent Johnson plugin, but I can not see how that plugin can help me with seeing if arguments are annotated with [NotNull]/[CanBeNull] directly in the intellisense-box?

As far as i know it has the following features:

• It will warn you about every reference parameter of a method/property not attributed with [NotNull]/[CanBeNull]. In doing that it will correctly process implemented interfaces and base classes.
• It provides context actions on method parameters/properties for adding the attributes (Isn't that what you meant with the intellisense-box?).
• It will not warn when the code flow dereferences a [NotNull] value (Resharper alone would normally do).
  
• It will automatically add an [CanBeNull] attribute to a method parameter when you do the check if null context action on it.

I see, and those features are nice for a plugin. But what I miss is a way to visually see in the intellisense-box (Ctrl+Space) if a method and/or its parameters are annotatet with one of those [NotNull]/[CanBeNull] attributes. As far as I can see, this is not part of the features of that Agent Johnson plugin.

Ah i see,

Probably plugins can't extend the intellisense box content. Resharper would have to do it natively.

I am using NotNull and CanBeNull in a current project and it turned out to be useful for documenting interfaces and catching possible null reference errors. So i would also support a feature request for value analysis handling directly in Resharper.
