Add an option to View Settings to apply changes to all resources/tabs, or only to that resource.
My main concern with this is that font sizes are not consistent between different font scripts. Greek fonts appear smaller than Latin fonts. And I need to make Hebrew fonts larger than Latin or Greek fonts in order to easily read the pointings. Right now, if I increase the font size in a Greek/Hebrew resource, it increases the font size of all resources, making the font in English (Spanish, French, etc.) texts too large.
