I think I welcome the additional information.
But it is not quite clear to me what I should do with it and adapt my workflow accordingly.
Here is an example of 13 selected files with apparently varying embedded pictures:
The pictures in the grid look the same to the naked eye.
I added 3 columns so that the picture properties could be investigated at a glance and the result of that check is:
1 file has no embedded picture
13 files have an embedded picture with the same dimensions.
11 files have a picture of the mime type PNG
1 file has a picture with the mime type JPG.
1 file has 2 embedded pictures.
But this additional information can only be found with the already existing means of checking the file properties.
The maximum number of pictures in the grid seems to be 4 - so if more pictures occur in the files, then these would not be visible. I have not found a way to scroll through the list of pictures.
I also selected just 2 files with a total of 5 embedded pictures. 1 files has 4 embedded pictures, each set to be a different picture type (front, back, leaflet, artist).
I see 4 pictures in the grid. But I don't see an indication that there are more pictures in the pipeline. Or that some of them are not front pictures.
I don't want to appear as feature creap - I am just wondering how to make best use of the new function.
@Florian: Perhaps some more background information would help.
