Two things: First, we have a preview available showing our Deluxe Thule pack (GM screen, poster map of Quodeth, and reference cards), if anyone is curious. You can see it at http://www.sasquatchgamestudio.com/thule-gm-screen-and-reference-cards/
Second: One of the reasons why 5e's short rest is an hour compared to 4e's 5-minute short rest is simply the aesthetics of the "adventurer's workday." It bugged the heck out of us (meaning, WotC when I was on staff there) in the 3e era that most PC parties blew through their resources and stormed four or five rooms in about ten minutes of elapsed time. So we had an idea that giving people a decent suite of powers that recharged every encounter might help them to adventure heroically for more of the day before camping. But in practice, 4e parties did the same thing, and maybe had a 20-minute adventuring day. So one of the reasons the short rest in 5e is an hour is simply to encourage PCs to spend all day exploring a dungeon, making the experience match up better with the books and films people think about when they think about fantasy adventure. I was part of the 5e design team for many months, so I participated in those discussions. Now, 5e does a much better job than previous editions of making players decide to use or conserve those "short rest" powers, just because any DM worth his salt can decide whether the PCs can sit on their duffs for an hour in safety or not. But it is something that plays differently at different tables.
Hypothetically speaking: What would you guys think about saying "3/day" instead of "1/encounter" or "1/hour?" That's close to the same frequency and fairly agnostic about encounter pacing. I imagine we might want some boilerplate like, "3/day but not more than 1/minute" or "3/day, but not more than once against any given foe because he's onto your tricks after you do it once."
