Allow filtering of marks/counters in detailed graph
In the "summary" graph at the top you can filter out specific sources. It would be nice if you could do the same in the detailed graph too.
Ideally we should be able to filter things even more. You can use the range selection to zoom the graph in on some particular time range, but if you have a lot of sources of data you need to scroll vertically a lot to see everything. For example, I would love to be able to filter out based on the message itself (but not the details, if that is stored separate at this point). Maybe have a "hide" button in the Details sidebar.
Of course, once things are hidden you have to show them elsewhere so you can make them visible again, so you probably need a toggle between filtered and non-filtered view.
