#181 Preferences doesn't get saved in Mac

[Cloverr]

I have been using it for some time and it's great for reading ebooks, but the preferences doesn't get saved, after i reopen application the old preferences get deleted, I have been using MAC OS X, El Capitan, also it would be nice if there could be some sane defaults preloaded, when i currently open epub files the text is too big and if I change setting too many times, sometimes the application doesn't respond at all.
