AT:

• It is possible to select percentile aggregations in the following views: 
  • Process instance
  • Incident
  • Flow Node 
  • User Task
  • Variable 

• Aggregation options are split into two groups (three in cases of user tasks) with the median option represented as P50 '(median)' and not in the basic aggregation option set. 

• When switching to a configuration to something that does not support percentile aggregations, ie. Group by process, only the basic aggregations are visible. 
  Note: Median aggregation is in the percentile list, and therefore not shown at all. 
• When displaying a long list of options, ie. for User Tasks, display full list by default and a scroll when necessary.
