But if you want to make a temporary change to a bigger line spacing, you can't. Or if you are sharing the library with your family and they like different settings. When I fiddle with an epub, I like to remove as many of the hard-coded settings as possible. That gives the most flexibility when reading the book. For line spacing, Kobo's minimum of 1.3 is almost right for me. I'd probably use 1.2 if it was there, but it isn't enough of advantage to make me hard-code it.
And for anyone who wants to know, the line spacing settings are: 1.3, 1.35, 1.4, 1.6, 1.775, 1.9, 2, 2.2, 3. I have no idea why those numbers, but they have been like this for a while.
