I hope you arrived at home well.

Today, i raised the plugins of our productive Moodle instance to use both the Vienna programmed multilang2 extensions.
Calling out once again that you may comment on the pull requests so the maintainers will hopefully incorporate them:
If you'd think you want to help pushing this, probably the best thing is to go to the pull requests https://github.com/julenpardo/moodle-atto_multilang2/pull/36 and https://github.com/iarenaza/moodle-filter_multilang2/pull/14 in Github and add a comment there pointing out how this could help you. I especially think of the Graz people (Nora and Franz maybe? Sorry if i were wrong!) I speaked with late at night: please do this.
For the Atto component – that's the button in the toolbar which offers the 'other' option – the Pull Request has beeen accepted. I turned out the plugin development has probably been handed over to another developer on another Github Repository. Kepa Urzelai seems to be the man now. Here's the accepted pull request: https://github.com/KepaUrzelai/moodle-atto_multilang2/pull/2
Still to be done: the https://github.com/iarenaza/moodle-filter_multilang2/pull/14 pull request. Encouraging comments to the developer there, Iñaki Arenaza, still very welcome.
I just have learned that the second pull request has been accepted, too.
This means that this functionality is now available (https://moodle.org/plugins/atto_multilang2 and https://moodle.org/plugins/filter_multilang2) publicly and out-of-the box in this plugin (give the guy a couple of hours to bake a new release in the latter, please). Thanks to all project contributors (Eva Dörfler, Kathrin Osswald, Mihail Bojonca), the plugin maintainer (now both are maintained by Kepa Urzelai) and big up!
