Hi... I jump in here to...

At risk to be the "old goat" of the pack. Started 1996 with Net Objects Fusion, that in this time was the (as far as I know) 1st object-oriented software for web production. Also had a version of "Front Page" that I tested out but left in a year. I was with "NOF" until 2015 when I suddenly noticed they ended all development and support, so I in panic started to look for a similar software.
Then I in grace found 90 second website builder that I a couple of month later discovered in fact was Wysiwyg Web Builder, so changed to it because the update frequency was better. NOF and WWB in fact have a lot in common, but also some major differences that can be studied.
When reading this post I also had to check up the NOF software and I got surprised... they still sell the software as it ended 2015?? Undeveloped and unsupported! Really bad.
One very nice future NOF developed when the CMS systems like Joomla and WP entered the market was a so-called rollback system, were you could install this complementary software (payed) to the original software as a plugin (extension) and a separate (free) software for your customers for them to handle their sites (only their own site). You could from the original software lock specific sections and objects so the customer would not mess up the structure and design... and some more good futures. When working with the site it was saved on the web server in the rollback system in choosed amounts of backfall levels for both backup and the ongoing project for all separate editors to manage and continue the work.
I think this was a very good workarround for CMS and could be something for Pablo to check in to
All that said... WWB is the best
