The configdir also holds things like color profiles, watermarks, all the settings done in the preferences, the information what modules are shown or in favourites, what's expanded, ... The library on the other hand has (as you already said) the list of imported images, their tags, ratings, metadata, and all these things. So it might make sense to have several collections (either while developing or to help organize images) while keeping the configuration the same. > Actual question: Would it be possible to change only the photo > collection library > but keep the same pattern of presets, options, styles, etc. with a > command line option?

And here you pinpoint the one flaw in the current design: the library also contains the presets and styles and also the list of existing tags. We will eventually move that to a different database so you can easily switch libraries, but for now that's not so easy (one could use a shell script wrapper around darktable to sync the database tables so if anyone feels lucky have fun hacking :) ). > Thank you very much > > Y.
