Allow thumbnailing images at import
Not sure the title is explicit, feel free to rename.
When importing files in darktable, thumbnails are generated and cached.
However only the thumbnails of the visible files in the lightroom are generated.
This means that for a big set of files when the user scrolls he has to wait for the thumbnail to be generated. I find this very annoying and would prefer that all thumbnails are generated during the import process.
Maybe an option "generate thumbnails at import" would be appropriate? This would increase import time but improve usability.
I embedded a little video to illustrate the feature request; at 15 secs you can see that when scrolling the thumbnails are missing and thus being generated.
I would like these to be generated at import time.
