Have you ever opened up Tweetie (2), just to see that there are some missing tweets, represented by the zigzag? You can easily tap the zigzag, but then you lose your place in time (if you read from the bottom up like I do). Well, I stumbled upon an easy fix for this. Simple slipe horizontally across a tweet with the zigzag visible to bring up the quick menu, and THEN tap the zigzag to load the tweets. They will load, and your location in the tweet timeline is right where you left it. I know this won't apply to everone, but it's sure nice to now if it applies to you.
