Andrea, maybe a new section in the manual should be started in how to accomplish some task like it is done in other NLEs.  For example, as Andrew pointed out about "gang mode" working like expected for difficulty in usage "because of the audio tracks being separate from the video tracks".  And include clarification of "edit" versus "clip" / differences and usage.  I would be useless in creating this new section as I have never used any other NLE.

The manual has mostly been based on the old-fashioned "Reference Manual", that was published by the manufacturers of big computers like CDC Cyber, IBM mainframes and Cray, rather than a "User Manual".
