Editing line-by-line in the Sync Editor can be slow when you need to make the same change across several lines. Add a multi-select / selection mode so users can choose multiple lyric lines and apply actions to all of them at once.

This would make the Sync Editor much faster and easier for common cleanup and timing workflows, including:

• Multi-select multiple lyric lines (including Shift + click range selection)

• Shift timing for multiple selected lines at once (move them earlier/later together)

• Use the existing line menu actions (e.g., Split line, Merge, etc.) on multiple selected lines

• Remove/delete 2–3 lines (or more) in one go, instead of repeating the same action line-by-line

Some users signed up expecting this capability based on documentation/chat mentions, so having it built in would better match expectations and make bulk edits feel effortless.
