I've listened to the vinyl version all the way through. I was surprised that the track list is in a different order, and I found that I prefer it this way:

Side One:
1. Cobalt Blue
2. Deadman's Hand
3. Pangaea
4. Anchorage (here's where it changes, this is my favorite song on the album and I like it closer to the beginning)

Side Two:
5. Happenstance
6. Sunken Sun
7. LLC
8. Operetta (great song, but I didn't care for it as the closer, it left me with the impression that the album was unfinished)

Side Three:
9. On Angel St
10. Lunar
11. Insanity
12. Space Saviour

Side Four:
13. So Love May Find Us (this amazing song brings the album to a dramatic end, and it's so long it's gets its own entire side!)

I assume the Pangaea tracks were left off the CD version due to length restrictions, especially SLMFU. Now, I really enjoy the Pangaea ep, but Untitled #23 feels more complete to me in this order with those songs included.
