A better way to manage attributes and metrics

In Insights (GoodData) we had a "Manage" section and we could see listed all the attributes and metrics (default and customised). This was a very important area, where we could keep track and manage all of our customisations in one place.

In Explore, there doesn't seem to be a very good way to manage calculated attributes and metrics. You have to open up a query, then click Add (under Metrics), then click Calculated metrics/attributes, then click the Edit pencil on each one. This is very long drawn out, untidy process for managing these.
It's also odd that these don't appear in the Calculations section of the query.

Do you have plans to introduce a like-for-like feature in Explore so we can manage these metrics/attributes in one place rather than having to follow the steps above?
