This thread is probably gonna cover multiple items. Sorry about that!

Here we go:

When using the jeweler and you put an item in the slot for removing a gem or re-rolling the sockets, you can't put the item straight from the jeweler's slot to your equipped slot. Every time, I have to put it in my inventory slot and from the inventory slot, equip it. This little extra step isn't much, but it also feels a little unnecessary.

When right clicking to sell an item at the merchant, it doesn't always register as sell. so every now and then I click the same item multiple times in order to get the item sold. There's no consistency when there is an issue, But when you go through a dungeon and sell a full inventory's worth of items, that is noticeable.

When I try to use items like Entropy orb or Erieban Tear, it will sometimes swap the item rather than trying to use it on the item. It might be something about hitting the right spot on the item, but nonetheless it can be confusing.

Going straight from the merchant to the personal chest will result in the personal chest UI opening, but you can't actually interact with it. the X button is clickable, but it does nothing. Hitting escape won't remove the UI. Clicking the personal chest again, however, solve the issue, and makes the chest UI interactable again.

I don't exactly know how I manage to do it, but sometimes when trying to sell an item or read an item in my inventory results in the item not actually showing its statistics. I think it has happened more frequently while in a dungeon and picking up a new item, and trying to verify if the dropped item is worth swapping out with my current item.

is there a shortcut that allows you to swap the W key potion? right clicking only swaps the Q button potion.

These are the things I can think of right now regarding the inventory / merchant & jeweler UI! Thanks for listening.
