Adventure Journal has a lot of good information in it but it’s a mess to go through. Monsters should just be grouped by map with maybe a search box if you wanted to look up a specific monster so it is easier to organize and look over. Also would love it if undiscovered items were displayed as greyed out or something under the monster info so you know it drops something else for you to find(so you can know you need to farm it more for completion).
On the monster tab of the adventure journal there’s a search box at the bottom if you are trying to find a specific monster (it seems to be case sensitive for some reason).
The main annoying thing I find is it doesn’t tell you what map the monster is on which is silly as you must have already gone to the map to get the monster in your journal in the first place.
