Hi to all !
Happy to tell that Plasma Media Center has been improved a lot and have basic functionalities which is required in a mediacenter i.e Picture, Music and Video.

First of all when user open MediaCenter then welcome screen gets opened in full-screen (required) modes i.e picture, Music and Video. User can enter into any of these mode by clicking on the icons.

Suppose, User clicks on MusicBrowsing, now user can browse through his local filesystem and can play the selected song he wants and can continue browsing by using back button which is at top-left side of screen. At the bottom, in mediaInfoBar applet remaining time of media getting played is displayed.

Suppose user wants to switch to other mode, then he press back button and reaches back to its home directory. Now after pressing again back button, will reach back to home screen and switches to PictureBrowsing mode. Here, he can browse through the local filesystem and can view the Picture. Directory containig picture will show thumbnail of picture. User can view the picture by clicking on the picture.
