As years go by, technologies progress and design preferences change. In April 2013 I migrated the "www.cyclocross-store.de" from an ancient version of xt:Commerce to the recent xt:Commerce 4.0. The main concern was compatibility of shop and customer data. A configuration tool for custom bicycles was implemented as well as an advisor tool for narrowing the search of wheelsets depending on usage, body weight and other features. Only minor changes where applied to the default template.
By April 2014, the shop template was reworked featuring a modern frontpage layout. Work is in progress to create a blog plugin and backend newsletter administration tool. This is an excellent opportunity to dig into CSS, PHP and JavaScript.
