I've created a Google Chrome Extension with quick links to the components in the last PrimeFaces Showcase. Links are sorted alphabetically. Everybody who likes an alphabetic order of PrimeFaces components can download the file pfchromeextension.crx from here. Simple drag and drop this file into the browser window and confirm the installation. You will see a small clickable "PrimeFaces icon" on the top right corner. I've also corrected some link names in comparison to original ones. Enjoy!
I was also thinking about two links for each component - one for showcase and one for the corresponding page in the User's Guide (PDF). For instance, Accordion (demo | pdf). As far as I know, Google Chrome has a built-in PDF reader and can open PDF on every page you specify in URL. What do you think?
