My main complaint with the inventory arranger is that you can't sort stuff you've searched, and that is just totally...it almost makes me ask why even have the search feature in there? It's handy, and it helps me find the number of the item so I can go scroll through that massive list for it, but it's annoying that I can't sort it straight from there.
And the list view kills me. All of that scrolling is just...and those icons are tiny. They need an option to make it just thumbs of the items like in the customize avatar page. Things would be more easily recognizable that way.
Also, we can already select multiple items in the arranger. Just CTRL-click...and hope you don't accidentally click outside the box and un-select everything you've selected XD
A little check box or something would be nice to select multiple items to move at once.
