Wrike filters allow for a lot of customization, but I think they're missing a key feature: exclusions.
For example, on my dashboard "Tasks by Due Date," I have a widget called "Priority Today." The applied filters are: All Active, TO: Current user, Tasks to Do: Today. However, I would also like to have a widget on the same dashboard that is just the tasks DUE today. (The "Tasks to Do" filter includes any task that falls on that day. The "Due Date" filter is just tasks that END on that day.)
If I set both of these widgets up, certain tasks will appear in both widgets. It would be nice to tell one widget to not include any tasks that appear on another widget that I specify.
The same is true if you have a dashboard with widgets for tasks to do today, this week and this month.
Exclusions would also be useful for folders. What if I want to see everything I have to work on EXCEPT for tasks in ONE folder? It makes more sense to me to be able to exclude that folder, rather than setting up reports/calendars/dashboards for every single folder except that one.
