Some items in the GUI aren't accessible for translation (version 8348). The German translation is marked as 100% but some items appear in English (this usually happens with plugin items but this post is about built-in ones).

- Tools> Options> Calculation> "Approximately equal" operator accuracy (I'd add that it is the number of decimal places which must coincide for "equal" to be true)
- Tools> Options> Network> complete form isn't translated
- side panel: boolean: approximately equal and unequal callout texts
- Activation indicator, also the whole activation dialog.
