I have uploaded latexila 3.47.0-1 to the 7-day delayed queue with a change in Maintainer to the Debian GNOME team.
I have left Tanguy in Uploaders (in addition to me) and given him Salsa commit rights to the git repo which is now at https://salsa.debian.org/gnome-team/enter-tex If anyone else needs commit rights, let me or the Debian GNOME team know. I don't think we have expertise with TeX stuff at all, but we can maintain a package for a GNOME related app. Thank you, Jeremy Bícha
