However the disabled state is wrong here. The buttons DO work  
whenever an playlist is loaded (which is always actually, VLC cannot  
run without a playlist).

That is plain impossible. VLC is a cross platform application. Do you  
have any idea how much work it is to program such a thing for  
multiple platforms?

I agree, but without a shitload of new Developers for the VLC  
program, this won't come any time soon. We are way understaffed to  
take on things like this atm.

This shows how little you understand VLC :D
You cannot simply kill these buttons. VLC needs them simply because  
it DOESNT work that way.
