It could be, that I access the same source files from different pcs with different paths, eg nfs. So I would appreciate it, if a 2nd path is searched, if the files are not found in the 1st path. Also it could be, that filenames are changed, so kdenlive gets confused, eg. when the files are renamed, but nothing else changed. If a file / clip is identified by a checksum a renamed file would be recognized.
