Muon, the Apt package installer UI is in need of a maintainer. It has been split out from Discover and Updater which are application focused and to some extent work with multiple backends. Muon is package focused and covers the surprisingly important use case of technical users who care about libraries and package versions but don't want to use a command line. It'll probably move to unmaintained unless anyone wants to keep an eye on it so speak up now if you want to help out.
