There is room on the screen.They’re not mis-spelled, they’re abbreviated. Chris addressed this somewhere (FB or the Blog) but I couldn’t find it. If I recall the conversation, they made the decision to keep the disc etching to 6 characters. I think to ensure they didn’t show when you rotated the disc to the back.
The function blocks in the lower tray on the screen was limited to the size of the text because the blocks are so small.
I’m explaining all of this from memory of an old conversation.
If you want to argue that the screen should match the disc, I suppose I could buy that.
Either way, it isn't OCD.
