[Dumelle, Timo (E+K)]

Well, then how about adding the option to hide them?

[X] Hide folder without visible content

The only way I see for Digikam to decide a folder is "empty", is to check the folder contents, i.e. iterate over the files in the folder. That's what's happening now as well to check for new files. So a "hide empties" option will at best not add extra processing, and thus not help in start-up time.

It might still be worthwhile, in order to simplify the interface. Then again,
*not* seeing folders you know are there can also be confusing, it all depends on the users. E.g. I know that the albums in Digikam represent directories on the disk, so not seeing some only because there are no images would be more confusing for me.
