I've been playing the beta with a friend for a couple of days now and we have two suggestions to improve the game.
1. Put a button to sort the general inventory. Each tab is super convenient, but in the general tab, there are holes after selling equipment or handing in quests. A button that would order everything would be super convenient. Example: after pressing on the button, the general inventory would be sorted item group by item group (like the tabs) and within each item group they would be alphabetical. So the inventory would go from "potion B, ingredient, potion A, scroll, chest plate, scroll, sword, book" to "potion A, potion B, book, scroll, scroll, chest plate, sword".
2. Sometimes it's hard to see small items on the ground (keys, clams, pearls, gems,...). So it would be nice to have a button like the highlight characters to highlight all interactable items.
Just my two cents!
