01 - Weather and day-night cycle
It seems odd for a place to always or never be raining, and it would be nice to see areas at night.
02 - Increased party member limit
Only being able to have four party members is odd.
If it's for balance, some workarounds for that might be to increase enemy power or dice odds/reduce player power or dice odds with each party member.
03 - Highlight for all interactive objects and items
It doesn't need to be something that can be toggled (though that would be convenient), but being able to highlight every object and item would be useful.
Going around in games with point-and-click movement and actions to find small items isn't as fun as it is in games with manual movement and actions, and with the colors of the objects, items and environments, it's far too easy to miss things.
Maybe a spell or an ability with a medium-sized area of effect (or varying by spell/ability) that can be used without limits would be good, if the other option is not balanced.
04 - A menu to pick up items in an area
In Baldur's Gate III, items seem to be in piles somewhat often, and when they are, it takes forever to pick up all of them, especially since the characters keep running and standing over the items.
It would be good to be able to activate a menu to pick up items in an area with.
05 - Quest selection, and a line that leads to quest objectives
Where the next area or item of a quest is at isn't always obvious.
Again, a spell or ability would be good for that, if not an option that can be toggled.
06 - Indicators for what party members see
Sometimes I see the characters succeeded at noticing something, but I don't see it and miss what was seen.
Arrows pointing to those things would be nice.
07 - More character creation faces, hairstyles and scars
Since the player character's face is often seen in dialogue, it would be nice to have more options to make characters more unique and interesting to look at with.
08 - Real-time with pause
The gameplay in the first two Baldur's Gate games was somewhat fast-paced, and even though the turn-based system is good, it would be nice to have that in Baldur's Gate III as well.
An action-based system like Baldur's Gate: Dark Alliance would be great too, but that's probably far too much to ask for...right?
09 - An automatic item sorting option
An icon toggle in the player/party inventory menu to auto-sort, and/or an icon to manually sort based on the current sorting type would be helpful.
The current sorting requires changing sorting types back and forth.
10 - An option to increase/decrease the odds of favorable/disadvantageous dice rolls
It's annoying to have the dice land on "1" so frequently, especially in dialogue.
Having an option to just use stats and spells in dialogue and when using tools would be good as well.
11 - Increased character weight limit
I know that items can be sent to camp, which is very convenient, but I often keep a lot of items with my characters, since I might need them for dialogue, actions or quests.
Having markers (like the story item markers) to tell which items are important enough to always have in the inventory (for quests and dialogue, the items would only be marked when the quests and dialogues are not completed, while items for actions would always be marked) might be a better alternative if it's possible.
12 - Choosing which character speaks in dialogue
Currently, I never know who will end up in dialogue.
Even though I always play as the custom character, I often end up seeing the other party members speaking in dialogue as the main character.
A way to switch which character is speaking as the main character during dialogue or a way to select which character will always speak in dialogue would be nice.
13 - A way to quickly return to the inventory screen from books
Reading books in the inventory menus causes those menus to close, which leads to having to open the menus again.
It's very inconvenient when you want to read more than one book.
14 - More loading screens
I'm guessing that there will be more loading screens later, but some landscape loading screens would be nice before then.
15 - A party selection menu
When leaving camp, it would be nice to have a menu to add or remove party members, instead of having to go to each character to remove or add them to the party.
16 - More camera options
It would be nice to have options to tilt the camera, zoom out further, automatically follow the current character and return to them after a few seconds of not moving the camera around the map, and not stop character movement when using "Toggle Camera Rotate" to rotate.
17 - Skip dialogue and activate dialogue as separate functions that can be set to different keys
It's very easy to accidentally activate dialogue when skipping, and it's odd that the key for those functions can't be changed.
18 - Improved path-finding
Characters seem to often climb back up/down ladders when following the currently selected character and then stop following unless the character goes back to where they are.
Also, characters climb on objects to pick up items/activate objects, even when it doesn't make sense for them to do that because they're close enough to do that from where they are, or the path just doesn't make sense/takes longer to get to the destination.
19 - A way to call companions to the currently selected character
Having to go back to a party member that stopped following all of a sudden is tedious, and it seems to happen rather frequently.
20 - Manual movement option
Since the path-finding seems sort of clunky at the moment, I often wish that character movement was also able to be manually controlled rather than only being able to be controlled with point-and-click.
21 - Lanterns
A lantern that takes the belt slot and can be found or bought, and a waterproof lantern that can be crafted would be useful.
