Widget to show translation rates
Look at the bottom-right of http://sitracker.org
It is a small widget showing how much has been translated.
Having such a widget on our homepage would make much more users contribute translations.
Ideally it should be embeddable from Github Markdown and Google Code (maybe a dynamic image?).
It would also be a great advertisment for Crowdin.
The badge is nice but it's not enough
We've added the translation progress badge. Can be found in Project Settings -> Badge (tab)
However, the badge shows only overall translation progress. The badge is also compatible with widely used Travis badges.
Hopefully that will help a bit.
Thank you for sharing the idea.
