I come back with this feature ;). ( You can see here : https://sourceforge.net/tracker2/?func=detail&aid=1761929&group_id=133110&atid=726273\)
You asked if this is in SRD file, but I don't know how I can read this file...
I send my data in srd file.
I like this feature, thanks to it I know my form and my progress.
