MarsSeed [1] filed a deletion request for seexpr-qt5 [2]: Broken Python2 based old fork of seexpr, VCS package in disguise, but source development stopped since 2019. [a] Actually it is likely that this work has been upstreamed, because that code is using Qt5 as well, but it is also currently maintained, and uses Python3. [b] There is an AUR package for the latter. [c] No need to keep this defunct one.
