In my Windows system tray (next to the clock), Dropbox used to show that it was fully synced by showing a green check-mark over the Dropbox icon. This was really helpfull.
If Dropbox was offline, it would show no overlay icon.
Recently (and according to Dropbox itsself) this has changed, the Dropbox icon now shows no overlay if it is fully synced, but to me, i constantly think my Dropbox is offline, instead of 'fully synced'.
So the idea is: please bring back the green 'fully synced' checkmark. Or -at least- make it an option to show it.
