Maybe I am just late to the party, but thusfar my workflow has been as follows:
Publish, wait 30 minutes where I can't work, notice that there is a problem with text being wrong somewhere (in navigation, in notes, on the slide) correct, re-publish, rinse and repeat.
I usually have to publish at least 3 or 4 times, and sometimes as many as 10. (If I'm having a particularly mistake-filled day)
So... today I discovered I can change text (on menus, on slides, etc.) in the presentation.xml file.
This pretty much blew my mind in a "OMG I've been wasting sooooo much time" sort of way... so I thought I'd share. The file is pretty much everything in your whole course, and if you can figure it out, it seems you can change a ridiculous amount of stuff.
So ya, if you already know this, sorry for repeating. But if you don't, and your workflow is anything like mine, you're welcome!
