Overview of functions?

Hello

Does it exist an (quick) overview of the panels/functions with description of what that specific button, checkbox etc. does?

I know the wiki, but it seems that it mosty refers to an old version of Blender.

It is WIP though, some things are not in there yet, some are incomplete.
Other than that, you got tooltips for all buttons and fields.

If you want more, you got to buy some book or trail and error.
Remember, to trail and error for 2h can save you up to 10min of manual reading! :smiley:
