I’d like an easier-to-select-from drop down icon list please.

The current list on my iPad in landscape mode only displays 5 choices starting from the bottom of the list. That requires a lot of scrolling to see (1) if a relevant icon even exists, and (2) to select one if it does.  Also, many such drop downs in other apps work such that typing a letter scrolls the list to the first occurrence of an item whose name begins with that letter.  Really helps speed up scrolling.  So, could the drop-down be configured to show more items at once, and use a typed letter to shorten the scrolling effort please?
