Ctrl+C (and Cut) on selected songs now also puts plain text on the
clipboard — one "Artist - Title" per line, in the order the table shows —
so a whole playlist pastes into a message or a document. Pasting back into
a playlist still reads the songs themselves, as before.
The headings were set with setFont, which the app's own style sheet
(theme.apply_theme) overrides on re-polish — bold in a bare dialog, plain
in the running app. A style sheet on the heading itself wins. The test now
applies the theme first, as the app does.
Get Info has a Volume slider (−100%…+100%): iTunes' own per-song volume
adjustment, which the library already imported but never used. It scales
the volume slider while that song plays; a boost can't pass full volume.
Works on one song or several (Mixed when they differ), and undoes.
Get Info's Previous/Next buttons are gone: since the combined multi-song
editor they were always disabled (and blank in some themes).
The laser settings draw the rig — speaker and mirror, laser, beam, and the
screen at its distance and angles — as a small textbook line drawing that
labels distance, angles and dot size in place of the sliders' numbers.
Preferences section headings are bold and 2 px larger than the text.
