Hi @Caro1, there quite a few existing threads on this topic:
- Overview of all the projects in a list? - #2 by Julien_RENAUD
- Portfolio of projects - Overview
- How to overview all projects at once
Generally speaking, the best workaround is to multihome all tasks of all your projects into a “master project”. You can then sort this master project by project to help you visualise which task belongs to which project.
Hope this helps!
