Archive is not a bad idea overall, maybe it should be categorized somehow? Like per conversation?
Or, just remove it and, like you say, focus more on the Journal. It may be really hard to use Archives after several hours ingame. Even once those are nicely done - just too much content. Filtering, categorizing, sorting will not make the task easier, still hundreds of pages full of text.
Okay then, I really enjoyed the game in its current state and I just can't wait to see how it progresses. Great work!
