Library features are judged by one thing under pressure: how fast you can find a specific track while something else is on the air.
Search and filter
Search filters by title or artist in both the playlist and the library. The library adds category, subcategory and genre, which is usually the faster route — "the sponsor's bed" is a category question, not a title question.
Selection that tells you something
The playlist manager shows a selection status bar: a single selection displays its duration, and multiple selections display the count and total duration.
That total is more useful than it looks. Filling a gap before a fixed-time event means knowing whether four tracks add up to eleven minutes or fourteen. Selecting them and reading the total is faster than any arithmetic.
Long titles that stay identifiable
Classical and compilation libraries have long titles, and truncating loses the identifying part. Title and artist scroll on overflow — a one-shot animation when the text is wider than its column, replayed on mouse-over.
On-Air Mode suspends these animations. Useful when browsing, unnecessary when broadcasting.
Speed at size
Playlist, playlist manager, history, statistics and library grids all use row and column virtualization with recycling. Only visible rows exist as visual elements, so a 5,000-track library scrolls like a 200-track one.
Metadata loads lazily too, so a large import shows rows immediately and fills in tags progressively rather than blocking.
Knowing what a file really is
Right-click → Information… gives general fields plus a technical panel: codec, sample rate, container bit depth, and the decoded format, channels and bit depth.
The decoded values are what you want when a track sounds wrong. A file claiming stereo that decodes to mono explains the problem immediately.
Selecting without accidents
Double-clicking a track row starts it — but double-clicking the scrollbar or empty grid chrome does not restart the selected or currently playing song.
A small distinction that prevents a genuinely bad outcome: restarting the song currently going out because you clicked slightly wrong while scrolling.
