I feel you, man. Thanks for the info about the web version, BTW. For my taste even the mobile versions of OF aren't a real thing and are acceptable only on-the-go, even the iPad one isn't rich enough. But the desktop app for OSX... That's a beast (the one I can't have, since I don't use Macs anymore).
Plus I see that the web version has no persistent offline storage / mode. That isn't going to work for me. So, not only lack of features might be a problem.
