Hi Box Team

This would be such a convenient feature.

I am sure it won't take more than a day for your Tech Wizards to figure it out.

The rollover might take longer because of logistics but it is worth the wait.

It will definitively help improve your already great product.

Agree. This feature would be helpful. 

I agree this is an important feature!  The thumbnail auto-selected by Box for the film I uploaded is nearly embarrassing.  I am hereby also submitting a strong vote for this request. Thank you.
