Yes indeed, being able to Monitor what Midhub is doing pipe-by-pipe (& with a patch like Joey’s, hear it) helps a lot.
It took me a while to realise the potential of MIDI Monitor; “New to Midihub” Step-by-Step.03 Monitoring incoming messages is all about this.

bit of a shame as Chord Memory seems so commonplace
When I’ve seen Giedrius discuss this ( 
needed), it seems like the memory part is less the issue than the recognition.
In other words, the chord pipe could work fine for someone with competent keyboard skills & timing like you, but it could mess up –{“Oh, you call that a ‘chord’”}– with the hordes of ham-fisted numpties like me (who would doubtless then blame MH not their playing!)
Having said that, I look forward to whatever Chord pipes do get built in ~ my bet would be new pipes that seem to be just be simple on the surface but make you go “oh Wow, now I can do this” further down the line…
