When the user clicks on a slide thumbnail, the URL changes to index that moment so if the user copies and shares the URL after click on a slide thumbnail, the URL copied will go directly to the correct moment.
Create the auto scroll feature on the slides thumbnails. The idea is that everytime the slide changes because of the synchronized playback, the thumbnails div will scroll to keep the current thumbnail centered in the div. The feature can be disabled using a checkbox.
Reposition auto scroll option and audio bar in the playback html

Audio control bar is bigger and aligns with the presentation. The auto scroll
checkbox is aligned with the thumbnails area.

Fix the position of media controls in the playback with video

The media controls area (acorn controls) was being displayed at the
wrong place in the playback of a recording with video. Now it's always
displayed right below the presentation area, doesn't matter if the
recording has video or not.

The media controls area (acorn controls) was placed in the wrong position
