Rather than relying on (1) opening an instance and (2) click on the bar at the top that opens the recurring expense editor, have a new tab in each group that shows a list of currently configured recurring expenses so users have an overview of what's active, and can configure the recurring master from there.

Currently, if a recurring configuration is active but the instances (initial and auto-created ones) are manually deleted, the only way to find the configuration master is from the Activity list, which might be confusing if a user doesn't know how to do this, but instances of recurring expenses that they thought have deleted, continue to show up automatically.
