Plans, yes but not sure when I'm going to work on it

Besides of being lazy there are also reasons for not extending the program.

I thought about creating an extended settings page to control the mplayer settings (by writing the ~/.mplayer/config file) but I'm not sure if that's really necessary. I believe the default mplayer settings are just right and only few users do really need to modify them. And they do get excellent support in this forum . Did I mention that SiB stands for simplicity is beautiful?
