Hello,
you are not alone with this request. I also would like to have a easy
way to generate the previews. I'd like to select the images I want to
generate and then hit a button or menu entry to generate the full size
preview for these. Then you could ctrl-a in your last import, start
generation, drink a coffee and begin sorting your pictures.
Doing this with an external tool works, but is not so convenient, of
course. And I don't know how to select the images that shall be
recalculated. It's not required to regenerate all thumbnails, just the
last import to work faster with them.

Hi there,
First off: Thank you for a great application. I enjoy using darktable
very much, and I feel that (with the latest 3.8) it got both better
and faster on my machine. Thank you! :-)
I have a feature request, though. If it is already implemented, then
maybe I need a pointer to a place in the documentation :-D But, the
request is: The ability (within lighttable mode) to enable preload /
pre-caching of full previews.
To put some more words on my work situation: When I am culling images
in lighttable mode, I go to full preview mode (shortcut 'w' or 'f')
and flick through the images. Whenever darktable encounters a "new"
image, it takes a second to render a full screen preview (or more if I
have already done some edits). It then caches it so the next time
(within same session) I show that image, it is shown immediately. This
delay, however, is a bit annoying when I flick through the images for
comparison. I therefor often find myself scrolling fast 10 to 20
images ahead, triggering a preview-generation, for then to go back to
"start" and actually viewing the images.
I would love it, if i did not have to do the little scroll back and
forth dance, but that darktable would just start generating previews
whenever I went into full preview mode.
I know there are some open questions (How many previews to generate?
What happens if the cached images hits the cache limit? What then when
you zoom in on a photo?) which I would be happy to discuss, but first
step would be to check in whether a) I am the only one with this
request? b) Is this already implemented (and I just haven't found the
feature)?
