One menu for Alerts
It would be nice to have one menu so you can change the alerts across all the scenes from one place instead of having to go to each scene to change each alert as this is incredibly time-consuming, especially if you have many scenes.
For example, if you have five scenes then you have to update your follow alert five times if you ever want to change it.

You can do this by linking your layers. Then in each scene, when you click Add Layer, you can add this linked alert layer and its settings will be preserved from the other scene in which it was created. A linked layer allows you to seamlessly make edits to any layer across all scenes from one scene. Linked layers share all properties except their position, so you can adjust the layer's placement to best suit the current scene you're editing without affecting its placement in other scenes; however you won't need to edit every other aspect of it. Hope that helps.
