@Bluetone Right-o that's my first draft of formatting - really simply, I tried to follow your flow and just group things into related bite size chunks that grab the eye but also make it easier for peeps to zero in on topics/concepts (not only on first reading but for future reference.)
Happy to change anything or revert to previous version (I made a copy ).
And I only spotted ONE typo (jell = gel), which is mighty, mighty impressive. Even with spell check I make plenty!
