You are simply awesome. I put together a site with CPT's and Custom Fields very nicely with the help of this great tool. Bonus: the client liked my setup, and asked if I could do the same thing on another of their sites. I said yes, but then the real cool thing emerged: I was able to export my Types stuff from Site1 and import them into Site2. Talk about excellent. Saved me a lot of time!
I get around, and I've got to say, your plugin is so nicely put together and easy to use. I have also experimented with Pods, which has very nice technology, but the documentation is slim, and you really can't hope to get any support, or at least I didn't when I asked on their "forum". Whereas so far at the rare times I've needed to look something up about Types, I found the answer in the docs!
For custom fields I've had a great time using Custom Field Template, which is a superb plugin. Yet Types gives you all that, CPT's, easy GUI features, and a bag of chips. ;)
I haven't even needed Views, as I'm very geeky, but I will certainly consider it if the need arises.
Super Job, Team!
