I'm sure a lot of you already know about this mod, but as I'm new to modding, I only recently discovered it.

I've always hated making notes outside the game (even if it's just a few scribbles on small notepad or a file in my phone) so this mod hits the spot!

I primarily use it to track dates so I know how long before it's time to return someplace and have everything re-set. My current build is crafting potions so harvesting and then coming back to harvest again is a strong factor is where the PC travels.

I also make a few notes on the alchemical properties of rare ingredients.

The interface for the journal is a little tricky if you don't assign keys for turning pages etc so be sure to take care of all that in SkyUI.

Hope you use it well!
