Feature request:Historic graphs and work+w'

Hi, 

It would be optimal if the device data screens could natively show power and heart rate with a graph carrying 30-60 seconds of historic data, plus to have items such as work, work prime and w' reserve.
For sure it could be added as an extension but I did not find any that provides this data yet.

I'm new karoo owner, the product looks great but with small enhancements I have no doubt it can lead the market as the rest of your sram products.

Cheers, many thanks.
