Hey Dirk-Jan,

That's why they invented disabled state ;-) (it's just like you're  
not playing any media file). It has to do with expectation
of a user. For example: in a super market there is no milk in the  
shells! What das the user do: it will ask a employee for
milk even though it isn't there! Same rule counts for buttons. It's  
better to have 'something there' all the time then appearing
and disappearing, this will only confuse a user. When you, for  
example select a movie file in your playlist, the play fullscreen  
button becomes active.

Way a head of you ;-P that's the current problem with VLC it has no  
Library Playlist Function (just like QuickTime Player) this is a real  
annoyance. We HAVE to fix this in the next version!!! Just like all  
iApps and others (Delicious Library, MovieGallery etc.) we can use  
this!!! If not, this will be the end of the road for me!!!!!!! You  
can select a Playlist from this button. It was only a demonstration  
with 20 items, those items will be of course: 'My Great Playlist  
Jazz', 'My Great Playlist Rock' etc. If ppl use 20.000 items and  
scroll through them with no 'lIbrary function' they are nuts (sorry  
to say that). Even Audion had this functionality!!!
I am not  person who thinks about now, but what will be... you an use  
what you want (or not). I am not hold back by progamming
questions. I just think, this can be done better!!!

I know, I killed that!!! If you press the button (Single Click) it  
will skip to the next media file. If you click and hold (Click and a  
you will enter fast forward/rewind modus (common this is a simple  
programming function). Lose the buttons and you willl gain screen-
