With the last release of Reports and Analytics we were able to allow you to use metrics created in Ad Hoc (Discover) to show up in Reports and Analytics and visa versa. We will continue to look at the others..

With the latest release of Reports and Analytics you can now get a metrics preview (by click on the info icon when you hover over a metric) it will show you the name, description, formula and an overtime report for the metric.

With the latest release of Report and Analytics all calculated metrics are global. Meaning you can use a calculated metric that you create from one report suite in another. All you have to do is uncheck the report suite filter in the metrics selector to see all metrics from a report suite.

As of the last release segments can be applied to calculated metrics.

This was added in our last release. You can now use metrics created in Ad Hoc in Reporst and Analytics and visa versa.

Great suggestion and we agree so we changed up the way metrics are organized in the last release (late last week) and it should make this a lot easier.

Great suggestion. We'll take a look. Continue to upvote this one. 

Great description of the problem. We'll look into it.

When you talk about segmenting on Calculated metrics. How are you thinking about it.Are you thinking about adding segments to calculated metrics (eg. Percent New Visitors [New visitors]/visitors)Or are you thinking about it as segments that say give me people that have a bounce rate of less than 50%
