the online view is not the primary way readers are expected to read the ebooks. downloading the epub and reading on an ereader (edit: where line height and font size are customizable) is the expected and best supported method

I think the point of parent was that the issue, the too narrow leading, is not a change that needs debating. On a mailing list, issue tracker or whatever.
Or if you think it actually was, this was not a project that I'd want to get involved in.
As someone who reads mostly ePubs, many of which suffer from issues this project aims to fix, I mean that in a very caring way.
i also don't think it needs debating. my point was that the issue, the too narrow leading in the online view, is just not going to be fixed unless someone points it out to someone that can fix it. if that's you, great! you can submit a PR to the git repo. or, if don't have the time or want to have to go find where the line height is defined, submitting a comment to the mailing list or noting it on the issue tracker will let a volunteer fix it
from my own experience, Alex is very amenable to improvements. the online view of the ebooks is just not used by probably anyone to actually read the books (just use an ereader app or device its a way better experience anyway) and because of that no one has cared to point it out until now
