Oscilloscope: trace averaging

[peterkinget]

Is your feature request related to a problem? Please describe.
It would be great to be able to do trace averaging in the oscilloscope of Scopy

It has been requested before, but hopefully this will bump the issue up.

Is there a way to up-vote this? I'm disappointed (just a little bit :-) that it is not possible with Scopy. Even my old Tek TDS220 can do it!
