I'd like to see a log/journal feature, where important events are automatically recorded to a text file. It would be nice to look back over a game and remember how it all played out.

It could include: births, deaths, tech level increases, island events (and any other important stuff I haven't stumbled across yet in my few days with the game!)

It could be organized by year, e.g.:
Year 5: Births: Pogo, Gonzo. Deaths: Niknik. Tech advances: Harvesting level 2, Fertility level 2. Puzzles solved: 2, 4, 5.

Or it could be just a running list with each event in the order of occurence.

Already, just a little ways in to the game, I would like to be able to look back and remember just when my farm started working and what year my dear friend Malik died.
