ALBUM feature

Reintroduce the ALBUM feature & make it a real MANAGING TOOL (also for PRINTING/PDF-generation) for œuvres (like e.g. Mozart's REQUIEM, where I want/need to set the individual "song" scores seperately, but:
a) based on a per ALBUM-defined score template,
b) after having finished the separate song scores, I drop the files into a DOCK-style window, which OPTIONALLY synchronizes the page counting (or via check-box, I don't synchronize it),
c) implement manual & automatic ordering feature (alphabetically, by pre-defined number (e.g. in project properties) (not being part of the song-name), make the song scores dragable (sorting),
d) give it PDF-option- & -preview buttons,
e) make it easy & comfortable to use
