Bug 4020

Hi

Over the past few days I worked on a Flatpak to provide claws-mail
(https://github.com/karras/flatpak-claws-mail).

It reached a point where I'd like to open a pull request to the Flathub
repository (https://github.com/flathub/flathub).

As this will require continuous maintenance, which I'd offer to take care of, I
wanted to check back with the dev team if this okay or if you've been working
on it on your end anyway.

Overall my current Flatpak works but will for sure require addtional
polishing. Especially how we want to handle the plugins properly (e.g. ship a
few by default, include via extensions, etc.).

Thanks for your feedback!

Cheers

Michael
