Since the list of addons is taller than the window, I don't see relevant information that happens to be at the top.
I also feel like it's superfluous to see the list of skipped every time, though it could be useful occasionally.

By displaying only the addons that are being updated in the current session, the output would become clearer.
Also by the amount of flickering I believe skipped lines are also being redrawn, so it could be a performance improvement as well.
