Is there WPMU Dev plugin that specialised in customising

Is there WPMU Dev plugin that specialised in customising menu, including creating mega menu, putting images or videos in the mega menu?

I understand that UberMenu is one of the famous plugin to do that and there are others premium plugins do the similar jobs as well. Any recommended free plugins (or paid ones that offer developer license) that have similar features?

Or, the best option is, WPMU Dev creates plugin that have same or more extended features for customising menu. I believe other members would be happy to have that plugin!

PS: I like UberMenu but I don't feel like keep purchasing new licenses for any new projects I am working on.

Thanks.
