I really like the features of HypermediaLab. It allows many customizable layouts for different interactive widgets. This allows to embed links in the video to access documents, urls, a pop-up information screen, and a few other options. It gives the ability to activate these features at any point in the video, and for any length. This is what makes the program unique from the others in my techstack. The only problem was the vendor's site was interrupted for a few days at time of purchase. It was resolved a few days later, on the date that he specified. For the interactive features, I have to give it 5 tacos.
