I think no GUI engineer has even seen Inventory/WH interface in la2. As a professional I can say only that it is just not designed to contain more than 20 items.
Why can't I sort my WH by category, name, weight etc. To see what is a thing is you have to hover you mouse over the icon and wait. To find a certain recipe among 100 other same grade recipes is simply a pain - check all of them.
Suggestion is to redesign WH to look like file view in Windows Explorer. You can switch view modes (details view, icons view etc). You may sort columns. You can actually see the names of the items, not only icons (which are the same for many items). Provide lookup search filter for inventory.
Ideally, I want to create my own categories for my inventory items and arrange my WH to those categories. Like - TOI Blueprint quest - all blueprints to this category, Reagent quest - all reagents to this category, etc.
