Revisit in another update with these IPB 4.2 features:
Add message support to videos content item.
Add promote/our picks support for videos.
Support recommended replies for video comments.
Support member filter (bulk mail/group promotions) for "Has added video?".
I've released a new version that adds vid.me and twitch previous videos support. I've worked on the promote feature in another app recently and brought myself up to speed on it. It will be added in a future update.
