I just started using Jaikoz and there's a lot of features so I might be missing this but is there a way to see something like a confidence percentage when Jaikoz wants to change something? And if there is, is there a way to change it? I would like to rely on Autocorrect for high quality matches but my experience with Picard makes me realize that I shouldn't rely on that for everything.
No we used to have a confidence percentage option a long time ago but it really didnt make much sense. I would consider Jaikoz matches are about 99% accurate regarding getting the correct song, and a little less regarding song and album depending on how particular you are about different album versions.
There are three things to consider about not breaking existing data.
1. If your existing data is generally correct you might want to change the Preferences:Remote Correct:MusicBrainz:Format:Only Modify if Empty options so existing is not changed
2. View/Show View Pane lets you quickly compare data before/after changes
3. No changes are saved until you do Save Changes so if you take the time to check the changes before before doing save changes nothing is going to get broken.
