MarsSeed [1] filed a deletion request for notify-osd-customizable [2]: Abandoned patched pkg from 2018; tarball created in 2016. Though there is a third-party upgraded patch from 2020, but the accompanying configuration utility, notifyconf, is a broken orphan Qt4 build, whose upstream is discontinued since 2013. Without the latter, there is no point in trying to revive this PKGBUILD. AUR/notifyconf's last comment is from 2013, and for notify-osd- customizable, there was one user comment in 2016 and one in 2020, mentioning a bug in this application's functionality. For the later, previous maintainer replied that they no longer use this package and cannot offer assistance or bugfix. Arch repo still carries the original Ubuntu variant of notify-osd. Safe to delete this deprecated pkg. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/notify-osd-customizable/
