did you intend to include all the changes from your other pr with tests

Yes (also the reason why in draft state; and an upmerge from 5.4/6.0 missing)

and this PR activates the relevant test

[HLeithner]

I personally would like to go into the other direction and removing the additional fields. We have a translation/override manager for this.

@HLeithner that doesn't let you have a multilingual admin. This does.

[HLeithner]

you will still have the translation in the overview, if you have 10 languages you have 10 lines, which is ... not so nice. (read the source code wrong) Alternative, show the translation as "inlinehelp" (always show) for example
