I used the following tracing pattern a lot for debugging purposes.
1) Add temporary TRACE_EVENTx statements into the code where I basically "print" values that I interested in.
2) Build chrome and install on a test machine. 
3) Run test scenario under tracing, then look at my temp traces, potentially sorting by arguments
4) Copy arguments to a spreadsheet and do some further calculations in the spreadsheet.

With the current version I can't find a way to see all instances of my debug events in a table format - it looks like I only get to select a subset from one of histograms. Also when a subset of events is displayed, all arguments are squished together - that is much less useful than before.

It would be great if I could still optionally see trace events the old way.
