Cht-core: Option to compare against the translation keys

[abbyad]

We should have the option to select the "Translation key" in the drop down list here:

That way we can compare the text to the translation key, which is useful when looking for those without a translation. It is also helpful when comparing an English label to the key, and also if the label was left blank:

Looks actionable, useful, and straightforward. Scheduling.

Not a priority - leaving scheduled but kicking out of the iteration.

hi @abbyad,

Do we want
two columns: Translation keys | Languages
or
three columns: Translation keys | Languages | Languages

Should we filter the list of translations by the selected key option?
This would imply having an empty entry key to re-list all translations.

Thanks.

@vimemo I think we want just two columns still. Add "Translation key" as one of the options in the left hand dropdown. I think it should also be the default option. The default option for the right hand side should be the configured default language.

[abbyad]

Ya, that's how I was thinking of it too. Thanks for clarifying.

@garethbowen, please review again. It looks cleaner now with your suggestions.

[garethbowen]

Merged. Nice one.
