## Review summary

Users praise Marker for its clean UI, ease of use, and strong value for teaching/presentations and quick in-browser screenshot annotations. Multiple reviews note good customization of colors, opacity and pen size. Repeated criticisms request a true highlighter mode, more annotation tools (text, stamps, straight lines, thinner pens), and improved performance on low-end machines.

### Pros

- Clean, sleek and user-friendly UI (easy to use)
- Very useful for teaching, presentations and quick screenshot annotations
- Customizable drawing options (colors, opacity/transparency, pen size and color presets)
- Reliable basic drawing tools that work well across most pages

### Cons

- No dedicated highlighter/transparent highlighting mode (cannot truly highlight text)
- Higher CPU/resource usage — can lag on older/outdated computers
- Limited advanced annotation features: no text mode, stamps/symbols, constrained straight-line drawing or very thin pen sizes
