I have some basic experience with UI design, including creating posters and designing my personal projects. I'm happy to work on this and can contribute effectively if you provide clear UI requirements.

Hi! I'm happy to redesign it, and since I'm also redesigning envoyproxy.io, I can ensure that we maintain the thematic look and feel.
