I just want to say that I absolutely love this plugin, especially when combined with Views (which I purchased).
While Views could use a little streamlining, these two plugins make for a very powerful combination that allows for extremely rapid development. I don't always use the templates in views, but I love having that option. I particularly like the Custom Field Groups options in Types, as they just make a lot of sense from an administrative usability standpoint.
Excellent work, guys.
One request: I'd appreciate if the admin menu icons fit with WordPress's existing style. The round orange icons are a bit ugly when mashed up with with all the sleek gray ones.
