Might it be possible to warn the user if the filter contains any unactioned filter after a Secondary Output Filter under a T-Filter?

Being after the secondary output, the filter can't alter that output.
There being no later secondary output under the same T-Filter, the filter exists in limbo.

The user might not spot such a scenario unless the log output is studied in detail.

Sure. It's probably only encountered by advanced players, but I agree, any gotchas that we can pickup are worth doing.
