the letter grid, with the empty letters dimmed and dead
mounted as jump-list
why it looks like this
The grid of letters a long list jumps from: squares with a 2 px border, the letter at 36 sp SemiBold, and a letter with nothing behind it drawn in the inactive colour rather than hidden — so the alphabet keeps its shape and your thumb lands where it expects to.
The phone only offered this once a list was long enough to need it; MIN_GROUPS_FOR_JUMP_LIST is that threshold.
