Request to automatically append the correct file extension when exporting a playlist #902
Description
Observation:
In the Playlists tab when you right click on a playlist and select "export" a popup is displayed asking the user where they want to save the playlist, however there is no default file extension appended to the filename and the user will not likely know what to save it as.
Expected/Suggested behaviour:
The filename extension should automatically be appended to the exported filename.
(Additional suggestion: When exporting a playlist it would be cool if the popup automatically suggested saving the filename as the playlist name being exported (e.g.: awesomemusic.m3u) if the playlist was initially named awesomemusic)
