Hello Linux Geeksters. As you may know, Xournal is an open-source application developed in GTK+, enabling the users to take notes, perform sketches and keep journals. Among others, it provides a pen, a highlighting feature, a text tool and a shape recognizer. Also, it has a special feature for performing annotations on PDF files (via the poppler library).
The latest version available is Xournal 0.4.8, which has been recently released, coming with a new feature for exporting to PDF, horizontal view mode, optional auto-save, enhanced icons for eraser and shapes buttons and bug-fixes.
