Application was tested using a fillable form. Form opening, completion, saving, and closing were flawless. Additionally, I tested the following text markup tools:
- Highlighter
- Strikethrough
- Typewriter
- Stamp
- Pop-up note
- Signature
All features worked well and carried over to the Windows version of Foxit (and vice versa). I'm not sure why, but when using the KDE PDF viewer (Okular), the stamp is not rendered properly.
