improved media controls.

The ability to pause and stop is great but further controls like repeat, ability to skip ahead or back by choosing area in media file, have media files open in one tab so you can play multiples without having to click on separate tabs.
Sometimes i needed to play more then one file (one on repeat)and I have to use external player to use repeat function and other times I would have to switch between separate tabs. Would be more beneficial to have them all in same tab with separate controls for each.
