In the lightsaber attachments section page 136-138, I would love to see the final product have all of the crystals in a section grouped together. So have a page of all the crystals that you can only have one of, and then list the rest of the attachments. Just a thought.

If there's any change to how modifications are done to 'saber crystals, I could certainly see putting them in their own section, as it would make it clear that said change is only applied to 'saber crystals and not lightsaber attachments as a whole.
