(For example, Map, Inventory, Block, HOLD, Ranged etc)
Those button and NumKey are on the right side both. If UI button are layouted as same, it is easy to understand as shortcut key. of couse even now NumKey can be assign to UIButton function. But the layout does not match.
(If now try same thing, it assign are may be not restlessly feeling. yes, I've tried)
and NumKeyPad can be add easy. NumKeyPad is very cheaply. If I put it on left side and use as a command pad, those command keys and left half of the full keyboard (WASDKey, "~"Key, TabKey) are get very close together. Operation during play becomes much more comfortable.
It is a only about the button arrangement on the UI, I think there is objection to changing completed thing. but I do not want put a sticker on NumKeyPad...
so I will send it as a feature request.
