Was just curious what default deb apps might be ready to go flatpak.
From a security/confinement point of view Evince or eog/shotwell seem like good targets. Of course gnome-fonts or gnome-calculator might be really easy to switch to.
Evolution or Brasero might not be worth installing by default depending on how much they are actually used (of course with Brasero that doesn’t give a good way to get that functionality…).
Flatpak exists (and maybe ready):
eog - can’t view items in trash
evince - can’t view items in trash
evolution
gedit - not all plugins may work
gnome-calculator
gnome-clocks
gnome-contacts
gnome-font-viewer
shotwell
Flatpak exists with apparent blocker
file-roller - possible issue #4
baobab - can’t delete things
gnome-logs, out of date flatpak exists
No flatpak exist
brasero
gnome-system-monitor
gnome-terminal
simple-scan
nautilus
