When customising a Dashboard Panel which displays a Projects query, there doesn't currently seem to be a way to specify that you'd like to list all of the Active projects, or all of that users Joined projects, while excluding certain defined projects.
One example of where this might be useful is if:
- You want to show the user their Joined projects on their dashboard
- But, you want to exclude "Group" projects which have been set up for particular groups in your team (or some other manner of projects, which are not actually projects)
Screenshot attached for clarity.
