Format
Fonts: You can import your own fonts
to use. Save your fonts to
Storage/fonts. When you open a
document, the fonts will be
detected. The settings such as font size, typeface, contrast, bold,
spacing only work on the newly opened documents but do not work on
the documents opened before the
settings.
If you want to restore the original format of the document, you can
tap the Restore Original Format icon.
