It's been awhile since I updated, and I really enjoy all the additional options and how much smoother it looks to be running. Great work!
Since Channels maxes out at 500 custom stations per m3u, I did make that setting adjustment. But man, things are spread out! I go from Station #3 to #53 to #94. I already have a Channel Collection for showing Live Sports, so it is not that noticeable, but when ESPN programs are followed by FS1 ones, it stands out. I know you are already pursuing a solution, so I look forward to that!
I think something you have put in is attempting to resolve this because now I see stations listed at the end of a program description:

However, it looks like anything that is ESPN+ is showing up as "undefined":

Also, would there be any way to get more granular control on something like Fox Sports? For instance, if I didn't want the BTN feed, could that be filtered out?
