Hello, first post on the forums. Pretty sure I got the correct section for this.
I have a large collection of books in both non-drm and drm (Sony/Kobo) ePub format. Although the majority of the books are nicely formatted and completely readable, they're all formatted like a regular book, with paragraphs starting with an indent and no spacing between the paragraphs. I find it much easier to read with spaces between paragraphs, especially after setting a book down for a bit and then coming back to it. I know it's quite possible to do spacing individually, but I was really curious as to whether or not I could just batch process the entire lot of books.
I was also reading into it a bit, and noticed that my reader, the Sony PRS-650, can possibly use a userStyle stylesheet to override the books default sheet.
