The example seems safe, but as +> you say, disabling synching should bs safe anyway. + +It's not an example, it's kind of a worst case scenario if there's no +easy and safe way way to enable synchronize_flags. I want to try +disabling flags, but if I change my mind and the only way to get it back +is to do a full notmuch dump/restore, that's a pretty hefty penalty. +Also, even if I do a full notmuch dump / restore, I'm not sure if the +notmuch new is necessary in the middle. + +So my question remains, what's the easiest safe way to re-enable +synchronize_flags after disabling it? (Safe meaning it won't change any +tags.) It could be that there's a very simple answer, in which case +sticking it in the man page might be nice. + +Thanks, +David -- 2.26.2
