It would be really great if page filters could be "shared" across (sub) pages.
Example:
Subpage 1 has filter for Date and Country
Subpage 2 has filter for Date and Category
Users apply Date filter in Subpage 1 (September 5th), then move to Subpage 2 and data is already filtered for the specific date because of the “shared” Date filter
This would allow users to switch to a dashboard from another with a more continuous kind of eploration experience.
As for other features, the feature could be disabled by default in order to preserve the original behaviour.
