A friend recommended Moon+ Reader for android and I was initially impressed by all the features and controls.
Then I checked how my own published books render in Moon+. I saw lots of weird things. If it matters, I'm on Android 4.21 for one device and Android 4.1 on my Nook HD+ tablet.
For example, I formatted a play epub which involved lots of hanging indents and centered paragraphs and verse, none of which seemed to render correctly. This play rendered correctly on ibooks, kindle, ADE and nook, but it seems that Moon+ Reader seems to disable css completely.
In options --> Miscellaneous, I toggled Disable CSS styles and checked "SHow "Preview with Publisher Formatting" button.
But it seems to make no difference. I see almost no publisher css except for bolds and italics.
I'm guessing that Moon + just doesn't support a lot of CSS and that "Preview with Publisher Formatting" just doesn't work. If that's the case, so be it, but I find it hard to believe. Also, I would appreciate any online references to CSS support for each ebook software. Maybe moon+ doesn't have a lot of mindshare, but I find it hard to believe that I'm the only one to notice these deficiencies.
This thread http://www.mobileread.mobi/forums/showthread.php?t=194146&page=11 seems to confirm that Moon+ Reader disables publisher defaults by design, but the setting to change that doesn't appear to do anything as well.
