## Review summary

Users praise LEO Dictionaries as fast, simple and reliable—especially for single-word lookups and via the context menu. The most-mentioned issues are that lookups open a new tab (many want inline results) and the lack of a quick activation shortcut or easier selection method.

### Pros

- Fast and effective for single-word lookups
- Easy to use—many users say it “does what it says” or is “perfect” for quick translations
- Context-menu integration makes lookups convenient while browsing
- Long-term stability and reliability reported by multiple users

### Cons

- Translation results open in a new tab instead of inline on the same page (frequent complaint)
- No built-in quick activation shortcut or simpler activation (users ask for keyboard shortcuts or multi-click options)
