All the learning resources are great. It's been years since I seriously simmed and besides an occasional foray back into FSX, I'm pretty rusty. What I'm also looking for though is a list of the top recommended companion apps, either (hopefully) free or pay. It may be a bit early for that yet with MSFS2020 but I already saw something called "FSX Follow" announce support. I have no idea what that is and I'll find out but I'm just using it as an example of what I mean. I'm wondering what other companion applications are out there as well. What do they do? What are considered the "must haves"? Is information like that available somewhere?
