Idea here is that while iterating over the structure to delete things at the same time also data is updated, cmp. the snippet behind `// reset selected formatter if needed`.
Would you prefer thus another dedicated loop for that, instead of one integrated?

What looks like a clean-up though is switching from a QStringList to iterate over to a QMap. With code which is reused from the old version, but actually a left-over from a method whose content is now distributed over multiple methods.

The old code used the sorted list of languages also for loading from the config, where though the sorting does not matter, so the new code which just cares for the loading iterates directly over the map. I don't think another intermediate change here helps tracking the changes?

I did not dare to also propose changes to the abstract interface yet. But followed your suggestion, added together with signal.
