A redesign gives the opportunity to grow and mature alongside the business. Over time, the types of interactions with users changes. The softwares should work the same may be. But it doesn’t has to continue to be what it was yesterday. In our Project, Lucia, Julian and me, we have redesigned the freeware "mp3tag" in time according to modern software and application trends. While doing it, content functionality and user experience were our primary concern. Redesigning an application is more complex than braining a new one, as there are certain unavoidable norms related to redesigning. It is like building something new from the scratches.
