Thanks. Yes, I mean when playing video files, not audio. It doesn't work. Unless you meant it only works with other video players windows', but that would be a bit limiting. Currently, I can't use Firefox or Word and watch VLC in a smaller window, since when you use these programs (and most others), VLC will not stay in the foreground. Usually when an application has an "always on top" version, it always stays on top, unless there's another application with a similar "on top" option enabled too (usually media players). VLC will only stay always on top, if an extra application is installed, like
PoweMenu or Actual Window Manager. (they can both enforce "always on top")
