I know there is a downloadable User Guide but I still think it would be really helpful if there was a Glossary of ML features and terminology somewhere on this site.
Not sure what you mean - can you start it for the features you already know well?
Feel free to start working on http://wiki.magiclantern.fm/Glossary
:D
I'm not using all the features of ML mainly because I'm not sure sure what everything does. I'd like to contribute to Wiki pages on features I'v tried.
What I meant by glossary is for example what is "Magic Zoom" and when will I need it and what will it do for me? But i guess someone will write a Wiki information document soon.
Press INFO in ML menu to find out.
The user guide or the in-camera help (through the Info button) should be suitable to learn what the features do in detail.
