The big reason for not having important TRS connections is that, more than likely, you'll accidentally use a TRS cable that you need elsewhere, and then you'll have to hunt that down from inside the patch. Not fun!
Anyway, row three:
Without the EML Fuzz in place, this now lets me add a decent logic section which can be VERY useful for altering clock signals, as well as CV level "pick-offs" via the Derivator (reads CV and outputs gates based on CV movement) and the Min/Max. The Boolean voodoo happens in the Frequency Central Deep Thought, plus I dropped in a dual pulse delay so that you can "lag" a clock or two for the Boolean module to chew on as well. Given that there's a bunch of clocking and sequencers in the fourth row, this makes loads of sense.
