My workflow is the following:
1. Always shoot jpeg+raw (jpeg for quick sharing, raw for "special" photos).
2. Copy all files into year-month folder.
3. Rename files to yyyy_mm_dd_original_filename.
4. Review files for keepers.
5. Keep jpegs and sync to Google Photos, archive raw files externally.

I am having issues with step no. 4. I can display either both or one of the mime types via filters. I am looking for the following solution:
- Some sort of a quick toggle (shortcut or button) to display only jpeg files for quicker review (raws tend to be slow and seeing the same image twice can confuse you). I use filters drop down menu, but I want something quicker.
- Treat a jpeg+raw image as one, so that I can discard the raw along with the jpeg.

Digikam is great and I've been using it for a long, long time, but still haven't found any setting to allow me to do this.
