Draw label on editor or change MenuItem name dynamically

Question

I've searched all over and tried many approaches and still haven't found a suitable solution. What I have is a custom menu named Build with the menu items Server and Client. When either is clicked it sets the define symbols for compiling to either SERVER or CLIENT. What I want is some indicator which mode I'm currently in. Ex. Am I in SERVER mode or CLIENT mode?

What I would ultimately like is a simple label in the editor that I can programmatically set when either menu item is clicked that will tell me what mode I am in but I couldn't find a good way to do this. GUI.Label only draws while in play mode, EditorGUI and EditorGUILayout is only used for custom editor windows, Handel.Label is only for the scene view while in play mode. I then tried to find a way to change the menu name it self but it seems you can't once the menu is created. I may have missed something so if any one has any ideas or the proper way to display a label somewhere in the editor it would be much appreciated.

If "Build/Server" menu declares SERVER and undeclares CLIENT and "Build/Client" menu item declares CLIENT and undeclares SERVER, you can write code:

 #if SERVER [MenuItem ("Server")]
 #else [MenuItem ("Cliend")] #endif
 static void ShowBuildState(){
 }
 
 #if SERVER [MenuItem ("Server", true)]
 #else [MenuItem ("Cliend", true)] #endif
 static bool SetBuildStateMenuItemInactive(){
     return false
 }

It will show you current build state by changind MenuItem name dynamically =)

It's not documented, but there is a delegate to which you can add a listener, SceneView.onSceneGUIDelegate. I leave the precise details up to you, but you could consider something like:

Create a static class with InitializeOnLoadAttribute and add an event handler to EditorApplication.update in its class initializer
In your update event handler, look for scene views in the current layout (e.g., undocumented static property SceneView.currentDrawingSceneView or SceneView.lastActiveSceneView) and if you find one you have not encountered before, cache it and add your onSceneGUIDelegate event handler. If any of the SceneViews in your cache are null during this update event handler, remove them your cache so you don't hang onto the managed wrapper for a window that has been destroyed.
