Thanks!
1. Honestly I forgot how to do that lol. I've been working on v1.3 which uses different method. Try to check on the other comments, I think someone already asked about it.
2. It's limited by the script I use to do the work, sorry can't do that.
3. Prefs -> Tools -> Lyric Show -> Lyric Saving tab -> find the option on 'save method' section.
