Mirrors the Feed tab's '[Fetch More]' row inside a drilled show's episode
list (My Shows depth 1): shows only while the show's cache holds episodes
beyond its loaded window, and advances just that show's window by 50 on
Enter (or automatically at the bottom in auto mode). Same fetchMoreMode
preference drives both behaviors. Adds a store-contract test for the
per-feed pagination path.
Adds a Selection Marker toggle under Settings → Preferences that
controls the ❯ cursor glyph on the focused row of every list.
Default off; rows keep a leading space for alignment either way.
Every list pane (tab strip, feed, my shows, discover, search,
settings, whitelist editor) reads the glyph through the shared
useSelectionMarker hook.
Also aligns the lead column across panes: page list rows drop
their extra box paddingLeft so labels start at the same column
as the tab strip (2 cells without nerd icons, 4 with), keeping
episode sub-rows aligned to the title.
Whitelist editor (Preferences > Auto Download Whitelist):
- input focus driven by nav.inputFocused() (SearchPage pattern) so Esc
deterministically defocuses and j/k/Space/Enter browse the suggestions
- suggestions react to mouse: click focuses the row and toggles membership
- no accent bg / no marker on any suggestion while the input is focused
- s re-enters typing mode; suggestion rows scroll into view
Search page: recent-searches rows get no bg and no marker while the query
input is focused (previously the focused row fell into the inactive branch
and rendered the border color as a background).
My Shows: w toggles the focused show in/out of the auto-download whitelist
at the show list (depth 0), with a whitelist marker on the row and a hint in
the preview pane (scope: whitelist).
Loading indicators: the braille spinner now carries a contextual label
(Refreshing…, Fetching…, Loading more…, Discovering…, Searching…) and is
shown in every loading state that previously rendered nothing — Discover
results, Search results fallback, and the empty Feed list.
Feed pagination: a focusable "[Fetch More]" row at the bottom of the flat
feed list advances every feed's loaded window by 50 episodes via the new
loadMoreAllFeeds/hasMoreAcrossAll store API. Behavior is a setting
(Fetch More: manual|auto, default manual) persisted in config.json; auto
fetches when focus reaches the bottom row. The button row is excluded
from episode focus so no episode is double-highlighted while it is active.
