I would like two things about backup changed:
1. Have an option to do backup whenever xlights is closed/opened (your choice). Optionally, do this as a differential backup (only changed objects since last backup).
2. Have an option to do backup whenever a sequence is changed. Sometimes, I just start down a path and mess up the sequences and say to myself - I wish I had yesterday's sequence to go back and take a look. But I didn't press F10 yesterday. I have tried to remember to save as - but that actually messes up my show folder and makes it hard to work with "the show".
