Perhaps more important is the ability to drag-and-drop a rendered equation from Keynote back to LaTeXiT and still be able to edit it. Pleasantly surprised when I discovered this feature.
I did not know this! Fantastic. Thanks a lot.
Ditto! This has been my workflow for a couple years now. LaTeXit is great. Almost completely replaced Beamer for me. However, if the integration is good, and I could do it all in Keynote, it would be even better.
