Feature request: Filter the parameters displayed with Events + Params

Love the current ability to view parameters on the plots. However, it would be very useful to be able to filter the parameter changes shown, so if you are only concerned about a particular parameter, or set of parameters you could see only those changes. The plot can get quite crowded with the automatically adjusted parameters:

The issue names the Events + Params plot but no files, tests, or entry points. Start by locating the plot’s parameter-change display and determine how the existing parameter set reaches it. Done means users can select one or more parameters and the plot shows only those changes without the current crowding.
