I notice if you decide to move some existing songs/setlists/racks to a different location, and update that in Tools>Options>Songs, the various files all still internally reference the original location with an absolute path. This might not be what people expect if they’ve just moved everything in their Documents/Cantabile folder somewhere else, as I just did.
It would be really nice to be able to move setlists/songs/racks to a different location and have them still reference each other correctly in the new location, maybe using relative paths, particularly when transferring Cantabile files onto different machines with different folder structures.
Related suggestion - provide support for a new file type, *.cantabileBundle (or suchlike), that’s basically a portable, zipped up set of folders/files.
