Man, I HATE when there's an analog stick note right next to the Square or right/square button since I'm using Tapsonic notes & it's blue, which is almost the same color as the analog notes, meaning I sometimes don't realize I need to hold Square down while holding the analog stick.
I think I'm slowly adapting to 8B, been able to full combo a few 7 & 8 songs (U.A.D & Ladymade Star come to mind), but my fingers still feel a bit tense & still results in me sometimes pressing it a bit too early. I can't get them to relax like my thumbs because I'm on alert for when the night L1/R1 note will come & what kind of pattern it'll be. Hopefully, it's something that I'll get used to over time, I think if I just stick with working my way up the difficulty ratings, I'll ease up over time.
Also, they really should patch in the ability to watch the hidden MVs in Collection.
