The quick translation feature is a very useful tool, especially when making use of a Google Translate API key to automatically translate items to different languages. There are some drawbacks though: When using the auto-translation, it always adjusts all items on the current page/tab. But if parts of the translation have already been reviewed by a native speaker, or if there are equation questions, which the auto-translate sometimes messes up, then you need to redo the whole translation process after the auto-translation was done.

This can easily be solved by having a checkbox for every item, which is enabled by default, but offers the ability for the user to disable the translation feature for certain items.

We could try to develop this and provide a pull request. Is this considered a helpful feature? Then we would give it a try.
