as a former part-time proofreader I feel it's my duty to let you know you have a typo on the Plugins tab within the Indexhibit Admin area!
you have:

Vimeo Input v1.0 (plugin.input_vimeo.php)
Adds ability to easily insert Youtubes.

Youtube Input v1.0 (plugin.input_youtube.php)
Adds ability to easily insert Youtubes.

I would imagine that the first of those, for Vimeo, is not supposed to say "Youtubes."?

not a dealbreaker but you might want to change that when you get a second...
