Currently, by default all applications that are launched are associated only with the activity in which they were launched. In many use cases, this is reasonable. However, there are use cases where it is not. For these alternative use cases, it would be good if there existed the option to associate all new applications with all activities by default.

Example: I use different activities to organize my widgets depending on the environment in which I use my laptop, i.e., with external monitor or without. Just because I disconnect my laptop from my external monitor doesn't mean I want to stop using all the applications I was just using. In the present system, I always have to remember to check manually that I want an application on all activities. And I usually forget to do that, and things become a big mess (e.g., I have applications running that I don't see anymore because I switched from external monitor setup to mobile use, I then try to start these applications again, with the effect that I get sent into the external monitor acitvity, and so on).

There are different ways in which this could work:
- The activity manager could have a settings option where one could set this.
- There could be a KDE control module for activities (right now there is none, as far as I can see).
- It might also be a per-activity setting, i.e., some activities could catch all newly opened applications by default, while others don't.
- Finally, it would be good to add a function that, when activated, associates all currently open applications with all (or with specific) activities.
