Bug 468714

Grouping of images is a very useful feature for me. I have several images of type .orf, .arw and corresponding .jpg and .tif in my albums and I group them by name and can apply geo-data, tags, ratings, ... consistently.
But I have some enhancement requests (or need some help to find it if already exists):

1. Order of grouped images.
After importing photos, I select all of them and do grouping by name. I know how to (by selecting single images in right sequence) control this by grouping single images, but I would like to define an order in case of multiple groupings (e.g. .tif top, .jpg second, .arw/.orf third, ....) to always see the developed image version first.

2. Filtering of grouped images.
If I filter for raw data, only the .arw images appear (the .orf images are second in stack). I would like to see all raw images of all grouped images for further processing. Always doing ungroup / group operations for filtering is annoying.

3. Drag&Drop support for groups.
I can copy/move all images of a group within digiKam. But when I drag a group into an external application (all 5 raw images of a series for HDR processing), only the first image moves over. Filtering for raw (see top 2) and drag the whole stack to an external program would be helpful.

4. Grouping along Timelaps / Burst
I don't know how this is supposed to work. The images of one bursts have different names, grouping along date works mostly, but requires re-check.

Thanks for this great tool.
