can't add a task during initial sync

i tried http://shybyte.github.io/unhosted-time-tracker/# with michiel@5apps.com

at first it shows up as 'you have no tasks yet'. when i add one, nothing happens. then when i refresh, i see my many tasks which i already had on 5apps have now arrived, and the one i added is (indeed) at the bottom. but it would be nice if it would update the view immediately, regardless of what it is syncing or not
