## Review summary

Top positives: color/theme customization, strong dark mode, and a feature-rich experience that beats built-in viewers. Common drawbacks: drag-and-drop reliability issues, lack of automatic OS-wide dark mode syncing, occasional UI blocking, and Firefox-specific viewing limitations that affect direct PDF links.

### Pros

- Color/theme customization (background and paper colors) enhances readability.
- Strong dark mode with high contrast and readability.
- Feature-rich with a wide set of functions, outperforming built-in Firefox/Edge PDF viewers for researchers.

### Cons

- Unreliable drag-and-drop opening; PDFs often open in a new tab or replace the current tab.
- Dark mode does not automatically sync with the OS/system; manual adjustments are needed.
- UI elements (tool settings) can obscure part of the page during reading.
- Firefox-specific viewing limitations require using the extension tab rather than direct PDF links.
