This idea is based on the following question:
It would be great to be able to set an application-wide variable. In my case I’d like to show the relation the user has chosen in a menu task so that the user can always check in what context screens are opened. This means you should be able to set this variable per-user/session. See above question for more context.
The screenshot below shows a possible location to show such a variable:

In my original question I could think of a few other possible solutions on where to show a ‘global’ variable:
- Set Breadcrumb everywhere to a fixed variable.
- Be able to change the username using a variable.
- Be able to change the task name using a (task)variable.
- Or, not only for tasks, be able to assign functionality to a menu (item).
I’d also like to hear if others managed to come to a solution or workaround for this or other ideas of how this should work!
