(Version 3.0.1)

1. Selecting Window > Playlist after launch results in just the titlebar and the bottom play-bar. (I.e., there's no rectangular field to drag-n-drop files into.)

2. A dragged in .m3u playlist files begins auto-playing. (I'd rather it didn't.)

3. Saving an .m3u playlist file of xyz name will squash an existing playlist file of the same name without alert/confirmation.

4. The Mac OS (El Capitan in my case) won't recognize an attempt to set (via the Finder's select-file/right-click Get Info dialog) VLC as the default for opening .m3u files

Regarding your points:

1. Works as intended. This is a minimal mode
2. Then do not drag stuff into the dropzone. If you drag into drop zone, it starts playing. If you drag it as an additional item into the playlist, it will not autostart.
3. Works for me, the file save dialogs asks before you overwrite file.
4. Works for me, too.
