"""Applications tab: horizontally-scrolling row of every app currently
playing audio (pactl sink-inputs), each with its own volume meter (or
independent L/R pair), mute, live peak bar, an output-device dropdown, and
— for whichever of those apps also happen to be recording (matched against
pactl source-outputs by application binary/name) — an input-device dropdown
mirroring the output one."""
