Practical Tips

Whole first, details later: First roughly mark the time for each sentence, then fine-tune
Use chorus repetition: Copy the already-timed chorus timeline and paste it to subsequent repetitions
Multi-person collaboration: Export LRC files and collaborate through version control tools
Backup habit: Regularly export backups to prevent accidental loss
