I can't wait for the next action update. It'll be so fun to see see Neville's spellsword in action. Hermione's nudge to dark potions is a good development too, we should see if further prompts bring up the Ravenclaw Circle. And now that our rampant paranoia about Ron has pretty much been proven unfounded we should also look into what we can do to power him up. I'm pretty worried the other two hadn't had their guardian visions. Harry should bring it up and see what they can do about it.
Researching up the diadem for Hermione and taking Ron to the chamber. Pick up the Secret of Atlantis or Heaven on the way. I really want to see if there's a unique interaction with taking him there. And honestly hell with him pocketing the loot - it doesn't matter in the larger picture. If they advance, so do we. And it would be a big show of trust that will make progress in opening up his shell. We picked Hard Mode so we can't really afford to slack off.
Also we need to make some major progress with the Inner Circle. Get them into Dark Arts. And take a few active steps to fix Harry's PR issue. It seemed like the student base didn't understand how his Astrology prodigy and working for Dumbledore ties to last year's events. Wizards are pretty dumb. We might need to do something more, flashy?
Also, any ideas about what we can do to progress Patronus to Infinite? Meta knowledge says there are tomes.. Would that be something to do with Helga Hufflepuff?
