- Significantly speedup hiding and displaying multiple rows by writing an
optimized single pass function for each. This reduces the number of tkinter calls required to the minimum. - Add a right-click context menu for sources. Supported commands hide the source, hide the whole group the source is in, and bring up a stat window. - Add a source stat frame that gives an event frequency table as well as the total duration for each event type that has a duration. This can be used to see, for example, the total time a thread spent running or blocked by a wchan or lock.
