When I add runes to the game equipments, the length of the rune bar is not long enough, so that when I turn to the bottom, the runes are not displayed completely and many runes cannot be added to the equipment.
So I have some ideas. First, we can add a reverse order option to the sorting of character columns. Second, we can put unused runes first. The third method is a little complicated. On the page of the runes column, only the types of runes and their numbers are displayed. Each rune occupies only one column. Clicking this column will further display which runes are not used, and which are used on which equipment.
I think they can solve the problem well by choosing one of the above three methods.
