While cleaning up my database (removing songs, replacing song files with other/better/reworked ones) I noticed another possible topic:
If you remove songs or replace song files, old setlists containing those songs  might be affected.
If you want a 'real archive', export as .msf and store somewhere else, outside of MobileSheets, would be the way to go. As propoposed before by otnt. No need to implement something in Mobile Sheets.

I guess I will just delete them....
