*Travel* Being able to travel with area transitions while one or many party members are on the other side of the map is very immersion breaking and incredibly cheesy (no the good kind of cheese).
*Trade* - Why have a "mark as wares" option if you can't sell all/set balance with wares (hopefully I just missed where the button is). - I need to be able to split items when in sell mode. Preferably also make it so that you can toggle other party members inventories and open containers (you keep in your inventory) to sell the stuff you got inside.
*Companions* - Should be possible to manage them a bit better. Tell them to follow, stay, turn AI off entirely. Alternative lock party order for easier disconnects/reconnect + dis-/reconnect full party for tactical situations or trap areas.
*Combat* - There is no way to force quit combat despite enemies being very far away. Should be a way to try and force quite combat (shift+space?) and let the game check if it's reasonable.
*Gear/lore* - Finding surface gear on all live drows is super weird. Also teh fact that drow gear doesn't disintegrate (no idea about 5e rules affecting, but weird due to how it worked in BG2).
*Quest log* - Why can I not scroll down using my mouse wheel?
