Trello - Mac OS X, offline possible?

Question

Trello

Now I use a bunch of Fluid + permanent Internet. In principle, it is convenient that Trello hangs as a separate application, but gets it when there is no connection to the Internet.
I'm generally interested in the question, is it possible to somehow enable query caching there or something like that? So that the changes are later applied when the Internet appears. Or not at all? Maybe someone has the same problem? I love trello, but without the Internet, it is useless at all as a fact. Any thoughts?
