Oscilloscope: show how long ago the latest "single"/triggered view was captured

[DeflateAwning]

Is your feature request related to a problem? Please describe.
I always with I could tell if a single/triggered view was captured very recently (i.e., I missed the change), or if it was a long time ago.

Describe the solution you'd like
A small grayout-out text box underneath or beside the "Run"/"Single" buttons. Text box would say "Plotted 1 sec ago" or "Plotted 3 min ago" or similar. It would only update secondly (or maybe every 100ms for the first 1-2 seconds), and would automatically change units as it gets to be a long time.

Describe alternatives you've considered
No alternatives exist, besides watching the screen. You can see when the "Single" button to switches from "Stop" to "Single" (as that indicates a Single event happened), but it's tough to watch if you're holding probes on a chip or something.
