QOL - Quality of Life
When in a fumble to get each material crafted for the item you are ultimately trying to craft, every second counts to be efficient.
I find that when I open my Inventory and go to search, I begin to type to search (The amount of items I can craft at level 33 is already quite extensive, searching is already a must) and realize I need to specifically click in the search bar. I don’t see that anyone would type anything while looking in their inventory other than their search parameters. Therefore, I believe when the inventory is opened, that the search bar should be instantly active and the player could literally start typing their search instantly. Putting their hand back on the mouse to click search is inefficient.
In addition to this, after having searched for an item, to start your next search, one clicks the search bar again and has to backspace or Ctrl+A - Del the previous search parameters before typing the new search. What should happen is once the search bar is clicked for the second search, the previous search text should be automatically selected so the player may type over the previous search.
Efficiency!
