I may have missed something, but I find the process of replacing a file with an updated version not explicit enough.

I might have 4 versions of a song, some of which may share a file, but I can't remember which is what. When I import a new version, if I use the same file name, I will get prompted with a replace existing file. However, I might have done something different in the past, I might be replacing a song with one from a different source with a different file name, or on the last import, there might have been a file name clash so it got renamed, but I've since deleted the original and so on, so I might end up with a new song.

What I would prefer, because then I can see exactly what is going to happen, is that I go into a song, I can confirm that is indeed the version I what to update, go into the Files option from the song, and on that file, click the three dots by the file name and select a new option Import. That would then offer me the usual individual file import, and the result would be that song file is replaced. (For completeness, it could warn if the file is used in multiple songs).

With the song selection approach I then know exactly what I am updating.

I'm trying to get my head around visualising this one and how it could be coded/debugged and maintained.

You say you may have several songs sharing a file so replacing the file could affect the other songs.
While MSP allows you to have multiple files in a song, you don't have to use that feature.
Personally, I wouldn't put that specific file into songs with other files, I would use a seperate set list for each of your "songs" that use it (you are effectively doing this manually adding it into a group of files). You can then use the edit tab to see which setlists a song belongs in and the best way to make your proposed change.

Using your current method, I believe that you could enter part of the filename into the main filter to see "songs" where it is used; you still need to know your library to determine how to update the file.

If you prefer to make changes within the song editor, you can always just remove the existing file, then tap the + icon and add the new version of the file. If the filename matches, MobileSheets will carry over the annotations, bookmarks, link points, etc. You can also long press a song on the library screen, tap the three dots at the top right and select "Swap File", but this doesn't provide the visualization you are wanting.
