Noticed some sorting errors as I was using this to re-organize my collection:
The following cards do not show up in the appropriate place alphabetically when looking at all cards from that particular faction:
LLDS Energy Regulator (seems to show up as if it didn't have the "LLDS" in front, but the other "LLDS" card is in the "L" section).
Push Your Luck (...but who cares. amirite?)
Mental Health Clinic
There may be others, as I didn't use it to re-organize HB, NBN, or Corp Neutrals.
