You're doing some great work here - very much appreciated. I have the latest version installed and it's working very well.
I the progress indicator as it gets the translation!
I suspect twitter and bing have some sort of legal arrangement, and we might also be required to display this based on the translation service TOS. If not though I'd rather just display "Translation:".
This is probably good enough for me - thanks! I suspect Microsoft and other translation services promise reasonable privacy, though would have to look at the TOS.
Cool! A link to simply "improve this translation" where twitter shows "wrong translation" link would be awesome! But perhaps for later if it proves to be complex.
But I'd orient the feature around "Improve this translation" language vs feedback which implies that someone else will be looking at it to approve the improvement.
This is a fairly big problem so unless you manage to fix it, please add this to the known issues!
