Hi,
One disadvantage SMPlayer has over VLC is the lack of alternative interfaces, like a webUI. The reason for this is that the -send-action command is . If the following actions were implemented, then it would be tremendously helpful:
-the ability to view the current song playing and its status (in easily parse-able form)
-the ability to view the current playlist
-the ability to select a song from the current playlist
-extra: documentation giving a list of actions which can be used (maybe in the man page?) - having to google each one individually is ridiculous
I don't think this would be a lot of work (maybe a few hours?), but it would really improve the functionality of SMPlayer and allow others to extend it further.
