This thing is very frustrating to use. I had the old version running and I was able to add the weather docklet on it, but it wouldn't update.
So I though it might have a conflict with the new version, so I deleted the old one.
Now on the new version when I click on add a new docklet, I don't see the weather app in that list.
All I get now is Clock, Calendar, Start Menu, Show Desktop, and Recycle Bin.
Edit* I uninstalled the program, rebooted, then did a reinstall, and still no sign of the weather app, even though it clearly shows it in the dock photo that you click on to get to the docklet settings.
As it exists, there's nothing in this version (that I intend to use) that my old version couldn't do.
I can see where the extra docklet options could be helpful to someone, but it's not for me.
