- I tried to use the show and hidden per scenario classes.
- I think it will be easier to review and maintain looking only at the install/inc/overview.html file
- I keept all the clone overviews to have a back button
- Some timing might be wrong, I must check it (espacialy for mac onces)
- Maybe for the steps implementation off the big steps (with green background) we could inline and share the strings (needs and steps)

The previous commit where WIP work. If I need next ones, I will try to do atomic ones.
