It would be nice if, when purchasing items (Market, Vendor, etc), the items were marked or notated as “new” or something, to signal that you have not yet had one of those for your journal. Maybe a mini-button to that entry in your journal or something. Or even just a little “+” icon in the corner of the graphic or whatever lol
This is a very nice quality-of-life improvement for players who are concerned with the adventure journal. Currently this information is made available to the player through many steps and the suggestion greatly reduces the amount of time and hassle spent deciphering this.
Currently:
Browse Market
See item that looks unfamiliar
Close Market
Open Adventure Journal
Check Item tab of Journal
Manually scan or quick-search for item in question
Verify item is not in your Adventure Journal
Close Adventure Journal
Re-open Market
Navigate back to said item in Market
Purchase item
If the suggestion were implemented:
Browse Market
See Item that looks unfamiliar
Note that the item is somehow marked as not being in your journal
Purchase item
