Ability to override font size and margins for epubs in reading mode

Some epubs are displayed with very small text and margins in reading mode making the books uncomfortable to read (screenshot attached). Most other e-reader apps allow you to change font, font size and margin size (screenshot of same book in a competitor app attached).

Same epub in competitor e-reader after increasing font and margins size…

In this case the text formatting overrides are accessed by the Aa button at the top of the screen but I don’t really mind where the option is

I think it’s fair enough to leave pdfs in their original layout but ePubs could be overridden. There could be a default override for all epubs or a per book override

Thanks
