Yes, please. Personally I do not really care, whether flatpak is used or not. For the
end-user this does not matter or is at least only a small detail.
In any case one should be install it from GNOME software. This is where all users should
(& can) install software from.
BTW. When I installed the flatpak from http://flatpak.org/apps.html
I only got the English
version… Maybe it is not yet translated? (to German)
