While I love the new QoE graphs that leverage the DPI technology in NPM, I'd love to see the ability to add the average, 95th percentile and to plot multiple applications on the same graph. This would make is much easier to show to application and network teams the correlation between TTFB, TCP Handshake and both data volume and/or transactions.
The average and 95th percentile would help with trending, especially over periods longer than the default 24 hour view.
