### Problem Description

On the PLAYLISTS tab of a channel, YouTube shows the date of the last update for some recently updated playlists. That's very useful, and it's a pity that YouTube doesn't show it for *all* playlists. But FreeTube does not show it at all.

### Proposed Solution

Show the date for as many lists as possible.

### Alternatives Considered

1. If YouTube does not report the dates on its page, try to find at least something out for the first playlist when sorting by Last Video Added.
2. Also show the upload date of the most recently uploaded video in the playlist.
