Gwennel Doc is a notebook that is WYSIWYG (What You See Is What You Get) and supports the odt open document file format.
Start by creating a new notebook, save it with a name and start typing. It is possible to just leave it at that, type, insert images, tables and links and have notes that are portable using the aforementioned xml based standard format.
However it is also possible to define presets or styles to use to format the notes. Either through the Format menu or by right clicking any one of Text, Paragraph, Bullets and Numbering and Table different fonts, colors, margins, line spaces, table widths and other styles can be defined for use in a notebook. These new styles will be available in the toolbar drop down menus for text, paragraph and bullets.
The default font used by the program is Tahoma but if a style is created to with another font for text then it can applied to any part of the notebook. Right click Text —> New Style and choose the font. Start typing and apply the style to it by highlighting text and choosing the style from the toolbar drop down. The same can be done to a paragraph for its font, alignment, background color, line spacing, border, and indentation. Bullets and Numbering can have number or bullet styles, different spacing, alignment and others (see image below). Similarly a table’s border, width, margin, cell colors (including alternating colors) can be saved as a style and applied via the Table —> Insert Table menu.
Gwennel Doc (version: 0.14) is portable and very lightweight, a few sample styles are available as a separate download but the main download comes with a sample and documentation that can serve as a reference itself.
