I am working on tcx-ls. It is quite niche, TCX is an XML file format used in sports tracking devices. Tcx-ls is a CLI that displays the information contained in the TCX file (like accumulated time and distance, etc.) in a more user-friendly way. I hope it is useful for many people.
I like the idea of a books list. This gives me new inspiration for books that I could read. Other languages like Spanish and French would also be great. :)
