It'd be nice if it remembered your hold time settings.
I'm really happy with the scroll feature, but I think it could be improved by adding an additional form of scrolling: tapping and dragging anywhere on the list to scroll through the items, like how you would scroll through a webpage on your phone (without the fancy stuff like inertia and friction). Currently, the scrolling sensitivity is an increasing function of the number of items in the menu, which is good for coarse-scrolling (for example, for scrolling to high level mage spells from Wind Strike), but it's bad for fine-tuned scrolling in large lists like the auction house listings (try it, its impossible to read all the items). What I'm proposing could be used in conjunction with the current tap-and-drag scrolling of the scroll bar in order to have tap-and-drag methods for both coarse and fine scrolling. This would eliminate the problem of fine-tune scrolling with the much too small scroll buttons.
Great update for android, solved a lot of the issues I had with the client. One thing that still bugs me is the items window. Maybe its just an issue with my phone (lg g3), but it really is a pain in the ass to skill. Lets take cooking for example. After opening up the item window and clicking on a shark, the item window stays open. This makes it a pain to cook the shark because I have to rotate the camera around in order to be able to click on the fire/stove. I figure its due to the small screen, but still having an option to be able to have the items menu "auto hide" after click an item in inv would make it easier imo.
*edit* - Another good option might be to allow us to change the size of our inventory scale. Maybe having options like Small , Normal, Large and allow us to switch between them in the options menu.
I think a much cleaner solution would be to single tap the inventory button to close it. Also, being able to open the inventory while keeping the "use item with" active would be useful.
EDIT: just tested it some more. It's really only the auction house listings that are subject to this. It's probably not worth implementing, as it works pretty damn well as it is for everything else.
