Looking good. I would let a player use this (if it made sense for my setting), and I think it would be interesting to play. Some relatively trivial notes:
True Visions:
Nightsight: I would define this more clearly in terms of penalties. Could be the same as Nightvision, or if you want it to be better (which is fine I think) you could say there are no penalties for anything short of pitch dark.
Merged Sight: there's a typo here.
Darksight: would be useful to specify whether this does or doesn't include Utterdark.
Mind Visions:
Mind Typing I, Finding I: typos here.
Temporal Visions:
Origins: "place of origin"
Intuitions: there's been lots of discussion of this spell. I would use the RMU wording which is "Caster gains a vision of what will probably happen in the next minute if the caster takes a specified action." The word "probably" is very important here.
Also need to add the spell types for three of the lists.
