Traditionally (= in Erminig for Diablo) there was the possibility of running Erminig in text-mode and some users defined periodical runs with cron. This is not really user-friendly, so yes the possibility to auto-sync/proper backgrounding is a good idea.

This is something that I can implement for sure: now the question is when Let's say that I will keep this idea in mind for the future developments, once I have stable release rolling.
