- Bug: view-only voting doesn't stop editing existing votes https://wordpress.org/support/topic/close-voting/#post-13061588

- Display weighted score instead of simple score (PRO)
- Show/hide/hover up and down votes
- Disable voting on nested replies
- Customize up and down colors
- Topics/Replies Upvoted/Downvoted on user profile
- Link avatars to their user profile pages
- Single topic shortcode?
