Now that I think of it some more, it may be more useful to simply add a "Hide App Events" checkbox.
This way I could check this box and it will immediately "hide" (not permanently remove) all the *** Activity and *** Service entries so we can only see the Log("") entries. But it is important that when I uncheck this box, the "hidden" app events are immediately displayed without requiring me to rerun the app to re-generate those app events. In other words, even if the app has stopped or paused, I would like to be able to check and uncheck this box so I can hide and redisplay the app events without having to rerun the app to see the app events.
This would allow me to just see my log events without all the "noise" of the app events, but also be able to instantly "unhide" the app events if I need to see the sequence of app events inbetween my log events.
