Hello.

Sometimes (or often) images in subfolders change. However, cached thumbnails remain unchanged. As far as I know, there are currently limited options for selectively deleting such thumbnails. It would be nice if thumbnails could be easily regenerated by right-clicking in the context menu.

It would also be nice if the directory was empty and an image appeared in it later, so that the thumbnails would be regenerated automatically.

thumbnails are rebuild for images with changed date/size when opening a folder in Browser

use 'Rebuild thumbnails'
in Browser > View menu - for all/selected files in current folder
in Settings > Catalog - for all/selected folders in Catalog


However, I would prefer 'Rebuild thumbnails' in View menu to rebuild subfolders recursively as well
