I usually keep both RAW and JPG next to each other (since some tools recognize them as being “the same”), but Tonfotos does not.
This leads to having a lot of duplicate faces in my collection.
At the top of my head, I see two ways to avoid this:
1) TF could also recognize them as the same (I guess based on filename would be enough?)
2) Similar to here ( https://community.tonfotos.com/d/44-disabling-video-scanning ) there could be an option to disable scanning RAW files
Both would avoid the duplicates, and might also speed up the scanning process.
