I found WireframeSketcher a must have addin for Eclipse, enabling me to complete very detailed wireframes for clients within the development ennvironment. When used in conjunection with the Eclipse SVN plugin it enables version control and effective design brainstorming. Of course WireframeSketcher is a lot more than this and has a comprehensive feature list including the ability to use master screens and 'Refactoring'; the ability to move screens and masters without the links breaking – a really great feature.

The fact that you export easily complete PDF files with all screens, hotspotted within the PDF and linked along with PNG files is a very effective way of interacting with customers in a fast and agile way. Read my blog entry to find out more… http://bit.ly/wireframesketcher
