If an announcement occurs I am interested and click on it (e.g. someone got a level up or intruders knock on my door). But after shifting my focus to this event I would like to go back where I was before (e.g. planning the next part of my mine). Maybe a button can be added to do so. This should also include changing the slice tool (events most likely happen on the surface).
The slice tool change is an additional suggestion but it fits to this suggestion. It is not useful if clicking an announcement and the location changes but I am still under the surface. Events that occur on the surface should disable the slice tool.
