So we use the explore tool heavily to analyze data. In the old tool something like the image was possible. I could look at my DAU for users filter by e.g. country, but from a specific cohort (so I didn't have to use the Cohort Feature here, just a filter). And then I would filter them on a design event, e.g. they skipped a challenge (an example design event). The new tool doesn't allow for any of this and greatly diminishes the usefulness of the Explore Tool.
