Right now Spark behavior is too intrusive, especially for those sitting on weak wireless link, or driving with their laptops from one hotspot to another. Spark will bring the roster window up showing it is reconnecting. So, many would appreciate to not see this al the time. I said "an option" in the title, but maybe we should just make it this way, not popping up, reconnecting silently. maybe Spark systray icon should change to gray-offline during the reconnect, so users will notice this if Spark won't be able to reconnect for a long time.
