Frankly, I'm not sure I'm up to that. I don't have much in-depth experience with this project, with the finer points of zsh, or with maintaining projects in general. I'm not entirely sure I could do a better job than nothing at all. However, even if I were more capable, I still don't think it's right to try to take over someone's project without some more clear sign that they are uninterested in continuing it.
