I also run OF on my iPhone and on the Mac (from a non-admin account), doing regular updates as soon as they appear.

I had the same question and a few more:

1. Can I delete all program versions of OmniFocus SneakyPeak except the latest w/o destroying some functionality or data?

2. Is the latest version allways the one named just "OmniFocus.app" or the one with the highest build code?

3. Should I keep one or two of the latest builds for security reasons (e.g. in case the latest build goes mad and I want to restore to an earlier build)?
