Maybe I will go ahead and upgrade then. I know when this happened with Google Play some people istalled 2.0.1 and left 1.7.2 on their system and they co-existed. I wonder if that's still the case or if I should uninstall 1.7.2 before installing 2.0.1?
I wish I could remember why I downgraded after 2.0 first came out. Past me should really write things down as present and future me often has memory issues.
