MarsSeed [1] filed a deletion request for turbowarp-desktop-appimage [2]: It might not make sense to have this AppImage based package, because it is a simple Electron-based application, and one of the core Arch developers, @muflone already maintains the AUR/turbowarp-desktop-bin package:
https://aur.archlinux.org/packages/turbowarp-desktop-bin The latter is also up-to-date, and uses Arch repo Electron instead of duplicating and bundling a foreign Electron runtime. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/turbowarp-desktop-appimage/
