Problem Description

#7007 added playlist duration in both the user and remote playlist views but the UX could be improved upon.

1. When viewing a remote or user playlist that isnt fully loaded we show a playlist duration number and update that number when user loads the next page. It’s not clear to users that the displayed duration only reflects the currently loaded portion of the playlist, which can lead to confusion or misinterpretation of the playlist's actual length.
2. When a short is added to the playlist we immediately remove the full duration of the playlist, e.g. playlist has duration of 17hrs and user adds one short, it will hide that number.

Proposed Solution

1. If the page has a 'Load More' button, add a '+' next to the playlist duration to indicate that the displayed time reflects only the currently loaded portion and may increase as more items are loaded (e.g. 44 min, 25 sec+ instead of 44 min, 25 sec).
2. Instead of removing the full duration, we could display it with a '~' symbol to indicate that it's an estimate, giving users a general idea of how long the playlist might take to finish (e.g. ~44 min, 25 sec instead of 44 min, 25 sec).

Alternatives Considered

None.
