Changing "Diary" section into something useful (Maps)

[Mudbill]

Is it possible to make the section to load multiple stuff? I'm assuming you can because you can just change a diary to an image and leave the original diary to read.

The background depends on the item itself, so it could work to have the diaries as well as the maps in the same section. You don't even need to use the diaries for this. You can use normal notes. I just decided to replace the diary section because it's not much used, and I like to keep different things separated (ex: notes vs maps).
As for adding more sections on the journal menu, I think that's hard coded in the game, so I don't really think that can be done. I'm not sure though.
