We have identified some things that we would like to see improved on our website: see the website-related tasks on Redmine.
Nevertheless, if you are a web or graphics person, you can surely find other ideas to improve the Tails website! Even if you don't plan to implement every suggested enhancement yourself, it may be worth creating tickets with your ideas so that others can benefit from your insight.
The source code for our website (CSS, templates and text) lives in Git.
