Support for offline mode - desktop client

Edit Subject

I frequently work in a disconnected environment and leave ScrumWorks (desktop client) minimized during this time. However it is very annoying to have the constant pop-ups about it being unable to refresh the data. I have tried turning off for each product the automatic sync but even then it gives a pop-up about having not refreshed its data in awhile. Can you add a way to truly put it in an offline mode? If not, just a simple way to disable the constant pop-ups without having to shut the whole application down would be nice. Thanks!
