I love that apps can autoupdate on OSX. It means when I log on in the morning I have the latest and greatest. But it's not all good. I logged in a couple days ago and I noticed that my shortcut for taking Droplr screenshots had completely changed. Droplr updated and somehow my old shortcut had been completely overridden.
Previously, I had my shortcut for Droplr set to command + shift + 4 but now that was replaced by the default mac screenshot shortcut. So I had to unset the default setting and then update the Droplr shortcut.
