I seem to remember changing the silk on the layout to say V1 Rev B a while ago.
I'm happy to have it be V2 Rev A.
Note: There's still a few labels that could be moved about to make a bit more sense, etc, but nothing ground breaking or huge.
Ok, perhaps we can update as we go.

I do notice that the ground plane fill isolation gaps seems to be slightly smaller. Did you alter the rules slightly? I say this because I now see ground fill on the bottom around E0-MOT, seeping in between the round pins on the motor connector. I'm not against the change, but the square pin on that connector seems to stop it being the same everywhere. Interestingly, if I remove the fill then re-apply it, they aren't there. Only if I load it from scratch.
Interesting, I didn't change any fill settings. I tried refilling the previous version you did and it produces different fill like you describe. So unless there are some hidden settings somewhere, perhaps this is due to different version of Kicad?

There is also not a huge gap around the top layer 100uF caps under the stepper drivers. There could probably be a slightly bigger gap between the edge of the GND pads and the +V_MOTOR line. Not a huge thing to change though, just a matter of getting the track widths right. Note: This was most likely the same on the previous revision, so I doubt it's much of an issue.
Also notice that an extra thin ground (on the bottom layer) that I put around P802 (the endstop header) vanished, but there should be more than ample grounding in that area now (I was being VERY redundant when I did that, just to be sure).
Ok, we can adjust that. I was trying to merge segments with a global track edit, but I noticed later it seems to completely remove some tracks it doesn't like. Possibly the algorithm thinks some tracks are redundant. The options in Kicad have changed from previous versions, so I am not entirely sure of what it is doing. There used to be an option to delete specific track nodes, I can't find that anymore. It's only a problem because the Drag command refuses to work on multiple segments.

Only other thing is the 5V rail between JP801 and P801 is thinner than the rest of the track along that area. The only way to fix that would be to re-arrange the tracks again around the hole near Due pin 21. Got an idea on how to do that btw(involves putting Z-MAX around the back of 5V_5, X-MIN between 5V_4 and 5V_5, running N-00000193 on top (like Z-MIN, but moving from top to bottom then back - adds 2 more vias), then moving some other bits around (mainly vias like FD_5V, D32, D43, UART2_RX_LV, and their associated tracks, etc).
Scratch that - Realised that we can move Z-MIN slightly nearer Due Pin 21, and then run N-00000193 around the left of the hole rather than the right. This allows us to move N-00000194 enough to widen the track at that end, but we still need to move a few other bits around (as before, mainly vias like D32, D43, UART2_RX_LV, and their associated tracks, etc).
That would be a useful change I think.
I'll take a pause for the moment while I do some other stuff, but we can collect up any other issues in the meantime.
