User Interface stencils
Web Detail Flowchart
The page title, page file name and page description area labels are editable. I added an example of how I use this stencil. Feel free to use as you like though.
Creative Commons
Need to add a Creative Commons badge to a layout? This stencil has them all!
Web Page Elements
Using the open-source "Bitstream Vera" font set and free icons from FamFamFam, you should have most of your common web page elements covered, including headings, form elements, content management function, image placeholders, etc.
UML 2
Additional UML diagram tools, esp. for Use Case and Activity diagrams. There is also a Domain object for class domain or namespace groupings in Class and Collaboration diagrams.
Windows GUI Design
User interface elements for the Windows operating system, in case you have to design an interface where Aqua widgets are considered a strange and mysterious concept, and licking them is totally out of the question.
Mind Mapping
Use this stencil to represent words, ideas, and tasks arranged around a central idea.
Web Form Elements
Edward Anastas has put together a handy stencil composed of often-used elements in HTML and web page forms: radio buttons, checkboxes, combo boxes, entry fields and text areas. Nice looking and Aqua, to boot.
Lines
Just a variety of line styles and colors, ready-made. Customize this with your favorite line-styles.
UX Activities and Documents
A stencil of UX activities and documents to illustrate the work that designers and researchers do. [originally created by Todd Zazelenchuk (Plantronics) and Elizabeth Boling (Indiana Univ)]
