The following bugs appear when I have done an initial download, and then, knowing I have more on the way, do an Update Now instead of just letting the indexing start:
1) If there are downloads waiting, the popup never stops claiming that it's still searching for them, even after the notification bar has already found them. (If nothing is found, the popup correctly says so.)
2) The new download message on the notification bar only shows for a few seconds, then it reverts to the 'ready to be installed' message, so you really have to sit staring at that bar, or you'll miss it, and will have to redo the Update Now.
3) The download size on the notification bar is considerably smaller than the one shown when hovering over the menu icon. (My preliminary suspicion is that the icon figure includes the size of the download that was done earlier.)
