Use-case:
I will be using Telescope as a replacement for the Debugbar package. However, I relied on the debugbar for the Query Detector package's output. For now I let the detector output to the log file, but then I noticed the Log page in Telescope is not very useful for stack traces / call stacks.
For example, the following log lines:

Are in Telescope shown like this:

Maybe it would be possible to group these into a single, expandable row? When it's collapsed like this:

And like this when it's expanded:

And all the details on the show page:

Just a proof-of-concept of course. But this would be more usable. If you could show it as one row, and click on it to expand the contents. Or view all the details on the "show" page.
