Are you a poweruser that wants to edit your raw gCalc save by hand instead of having to reimport for every minor change? To get started, go to Characters and click the wrench icon next to a character. At the bottom left of the popup, click "Edit Raw Save".
Disclaimer: I'm not responsible if you mess up your character. If you do, please re-import it from GCS/GCA.
Disclaimer: If you change this by hand, any import from GCS/GCA will overwrite your changes.
