+- Impact preview: pick a setup, see +/- weight and cost delta for each candidate
+- Candidate ranking (drag-to-reorder) with pros/cons text fields per candidate
 
 ### Future

-- [ ] Candidate ranking/prioritization within threads
-- [ ] Impact preview: how a candidate affects setup weight/cost
 - [ ] CSV import/export for gear collections
 - [ ] Multi-user accounts with authentication
 - [ ] Collection sharing and social features (public profiles, shared setups)
