One of my favourite early Shape 5 templates was Eden Rock and I used it to build a number of websites for an ERP Software company. Recently they requested that I enable the Arabic language on one of the sites but RTL languages are not supported by Eden Rock. Solution - revamp the site with Callie-Rush while retaining the original look and feel.
The new site is http://www.trueerp.ae
By comparison the old Eden Rock version can be seen at http://www.trueerp.com
The flexibility of Callie-Rush made the transition relatively simple even though some customization to the site css was required. At time of posting, the client has not added the Arabic translations but that bit is up to them.
