It expanded across the entire screen and the font was way to big for our site. Did not work with the theme.
I think that this app deserves more than 5 stars.
For 2 reasons
The most important that is absolutely perfect for the need of a small e-commerce that doesn't need all the more advanced features that Zendesk Help Center for example can give; while doing this, it gives you a proxy url that allows you to seamless integrate in your store, and this is a key feature; plus, it has all the essential features that you really need and at the same time a very easy way to manage and customize them; everything is so easy to setup...
It's almost incredible, but it's free. If I think that there apps that don't offer almost nothing and ask for your money... you find this great piece of code, and it's for free!
Really, really recommended. Thanks a lot Lukas from Help Center!
UPDATE April 6, 2017
Unfortunately I have to lower the rating from 5 to 3 stars.
I confirm the validity of the app but there have been two serious problems.
1. The verification code CAPTCHA suddenly stopped working. Software problems are common and occur and I can consider this acceptable even though clearly a program with 5 stars should not have these problems
2. What is really serious is that I have 4 well written email to the support by explaining clearly and repeatedly that the site can not be launched because of the problem of the app (customers can not write a message to customer service because the verification code CAPTCHA it works).
The support responded to the first e-mail then completely ignored subsequent email (one per day, not 4 on the same day).
The application is free ... but not for this should not work and the support should not respond to urgent requests.

Not able to customize and developer will not help you do it either
Easy enough to use but this has a very ugly interface.
