During the on-air presentation, the current slide indicator (the red arrow) in the thumbnail view follows to the right until there is one slide left on the right side which means that you can only see the very next slide in the presentation unless you drag the slider. Is there some way to show more futures slides without using the slider or right arrow on the slide? For example, can you lock the current slide indicator in the center of the screen so that you can see 7 previous slides and 7 next slides to make skipping to future slides just as easy as back-tracking to previous slides? I rarely back-track, but quite often need to skip forward. Currently, to even skip forward one slide requires a minimum of two clicks. I also prefer to see what's coming, rather than what I have already done. It gives me more warning when I have to prepare other functions such as turning mics on, queuing music, etc.
