I really like the log window tab on the interface which depicts what's being converted in a real-time fashion.
Recently, I used XnConvert to convert some Hi res pictures from my camera to a lower resolution so all I needed really was a batch-resizer (which XnConvert performs just wonderfully

However currently within the log window there is nothing telling me that I have made a 'Resize' setting before the conversion or as well if I have made other Image Processing settings in the "Actions" tab.
But mainly I am thinking as an idea for a feature if all the contents of the Log window could be auto-exported to the Output folder via a user enable/disable setting.... Plus maybe, all the details of the image processing settings made in the "Actions" tab for the conversion could be detailed in this exported Log text file too.
I'm thinking of a suitable generated filename such as this: converted_xnconvert_{date}{time}.log
==================
EDIT:-
Additionally the Log window needs to detail what 'Actions' were added to the converted images e.g. rotate, watermark etc....All these info's could go at the bottom summary of the log file's text file conversion list.
Just a thought.
