Finished up that Lady Blackbird campaign I mentioned earlier, which was a blast. I might actually be about done with feeling like I’m a mediocre GM — still had the same tension I always have right before a session, but we got through this one with zero delays on account of my stress levels, which is pretty good for me and I feel great about where our improvisation led us.
More to the point, I’m completely sold on Miro. I’d been thinking I needed to do a ton of work to make a Miro board useful, and that I’d need to be messing around with it a lot during play. This is in fact untrue. I just set up an image board for NPCs and dropped a couple of reference images in it (one map, one picture of The Owl), and that was immediately helpful. Later on, I added a couple of rules references. Again, useful immediately without any serious work needed on my part.
Also great: using it for links to our dice roller, Google Sheets character sheets, and so on.
