In case you use Omnifocus (I totally dependent on this piece of software to put some order in my life and actually GTD ;-)), it’s nice to know that there are some beta revisions released quite often by the Omni developer team that may fix some issues with the most current stable release.
I’ve just “fixed” some annoying bugs in the most recent stable version (19.2.) in Lion, and got some new Lion specific features (e.g full screen). I’m probably getting some brand new bugs too, but so far, I like living on the bleeding edge 😉
Nice tutorial on how to make good use of Omnifocus!
