* Adding items to a container doesn't start at the first empty slot, often an entire first row is empty. This could be fixed to avoid having to click any "sort" function.
* Adding stackable items - like arrows to a pouch - doesn't auto-stack the arrows of the same type. Don't need 4 lines of 1 fire arrow each, just auto stack them within the container.
* Some way to sell/barter items with a single click by using a modifier key - i.e., 'ctrl+click' could sell the entire stack instead of having to drag-and-drop the stack or click then choose some slider to set the amount.
* Inventory container windows could remember the screen placement and size. Hotbar placement of abilities could remember their spaces.
- So if we open a pouch we use for arrows, remember its coordinates and size on the screen instead of having to move it every time.
- If we equip a weapon, remember the slots on the hotbar we place that type of weapon's abilities at so, if we swap weapons (or have to pick one up again after command: drop or 'heat metal') we don't have to fiddle with the hotbars to get those abilities back in the slots we originally chose.
* Better (even customizable) filters for inventory sorting. 'Show me only weapons.' 'Show me only non-magical weapons'. 'Show me only vendor trash'. More consistency in quest-related items - all orange-bordered quest items together, all dyes together - currently it's a bit willy-nilly.
* Add items to 'wares' but no 'sell all wares' option (at least that I've found.) Seems an oversight.
* Specific gear slots for special-items. This is the torch I've equipped, this is the shovel I'm carrying. All other shovels and torches in my generic inventory I can sell without having to set aside that one torch or shovel. (And shovels, as a bug, not auto-added to the item hotbar when we have all "auto-add to hotbar' settings disabled.)
* In early access, could sort per-character even in the tabbed 'show all party member screen'. This appears to be no longer an option, and any sorting from the tabbed-party screen sorts all - bring back the individual sorting even on the tabbed-party screen.
* The little dot that shows a new inventory icon on books could be there until you've actually read the book (or parchment, scroll, note, etc). Doesn't need to go away if you've accidentally moused-over it for half a millisecond.
* Likewise, any generic lore book you have already read (A is for Azuth...) doesn't need that 'new inventory' icon.
* Nice we have a keychain, nice we can put quest items in containers. But we really don't need to carry that 'charred key' with us until the end of Act 3. Auto-remove all keys/quest items the moment their usefulness is obviated. (Maybe this should be a customized option for people with the curiosity of wondering, "Well what IS this key for?" long after it's no longer necessary...)
These are just a few things I've noticed over the course of playing and replaying that, if addressed, could smooth out the process of what amounts to micro-management and could increase the emphasis on what is 'fun.' Ideas and suggestions we'll keep rolling at ya, devs!

Thank you.
