Tap on "Add-ons menu"". Your current add-ons will be listed.
Tap on "Caption Manager" menu.
Click on "Edit styles". A dialog modal will open.
Use the rich text toolbar to customize the text of your captions. You can specify the font size, make them bold, italic, or underlined, choose a custom color, and set the alignment of the paragraph.
Changes made will be immediately reflected on the illustrative caption below on the modal.
Select or search for a font family from the dropdown selector.
Font family changes currently will not be reflected on the illustrative caption below the dropdown. This is a technical problem that happens because we don't have easy access to Google Fonts through the modal.
Click on "Save styles" button and wait a few seconds.
