Two things belong in different places, and they were in one.
Settings → Satellites now holds the setup: which satellites to follow —
the same two-column shape as the awards, for the same reason, since a
feed carries two hundred birds and an operator works six — and the
orbital elements, their age, the fetch, and pasting your own. Following
none still means every satellite with both elements and a frequency plan,
so somebody who has not chosen yet is not handed an empty tab.
The panel keeps only what a pass needs. A countdown to AOS, or to LOS
once it is up, because that is the number that decides whether you sit
down; a bar for where in the pass you are, since mid-pass the useful
question is not the clock but whether you are past the peak; rise, peak
and set with compass directions, because "rises SW" is a direction to
look in and 213° is arithmetic. Distance, altitude and footprint. And
approaching or receding, which is the sign of the whole Doppler
correction and the only thing that explains why the frequencies are
moving the way they are.
The countdowns run in the browser from two timestamps. Predicting a pass
steps the orbit across a day thirty seconds at a time, which is not
something to do once a second for a clock the page can keep itself.
