We are organizing our ToDos in Sprint-Folders/Projects by calendar weeks. So, there are Projects like "Sprint W07_08", "Sprint W09_10" etc. which are all located in a "Sprints" folder.
The tasks themselves do not have a due date but are set to backlog.
It would be great if there would be a possibility to create a Widget "Current sprint" which would filter like "All tasks from Projects which are planned for this week inside "Sprints" folder".
What's missing is a filter "is in" wich can be dynamic - not just a fixed folder/project. Like "Is in a Folder/Project with these properties: [Project/Folder properties]"
