Summary: The debug system CameraKeyControl of Unity.Tiny.RendererExtras is unexpectedly and undesirably included when Unity.Tiny.Particles or Unity.Tiny.UI are referenced in a project. Detail: I spent a couple of hours last night trying to figure out some unexpected camera behavior. I finally linked it to Unity.Tiny.RendererExtras via a few posts on this forum, but Unity.Tiny.RendererExtras was not explicitly referenced in my project. After a little digging I found that both Unity.Tiny.Particles and the new Unity.Tiny.UI package reference Unity.Tiny.RendererExtras in order to gain access to the MeshHelper class. Unfortunately any time that Unity.Tiny.RendererExtras is referenced it also causes the CameraKeyControl system to be automatically registered in the update loop and the debugging features of that system are included when the project is built. I believe that the automatic registration of the debug camera is undesirable if the rest of the assembly includes unrelated functionality.
