Hi,
I plan to use your page builder occasionally for web pages sections and not to build a whole site, so the best solution in my case is to integrate custom type modules built with your page builder directly in T4 framework... or go directly to building a page with your component, but I prefer to keep this solution as a last resort to stay as much as possible with core Joomla elements (articles or modules)

I'm quite perplexed by the code generated when I use "Add-ons" type items, with each element added an ID is added (even for a simple paragraph), is it really necessary?
I don't think this behavior is the same with "Blocks" type items, it seems that less IDs are generated...

Here is what I also noticed and which in my opinion could be improved or fixed.

It would be nice to:

avoid generating new IDs for each added item, this will allow to have a cleaner code
have the option to leave font-size and line-height property on inherit (as is possible for font-family property)
Since I use rem value for font-size and line-height property in T4 framework, it's annoying to have to set this value again in the page builder. Or did I miss something?
Please make rem value possible also for margin and padding.
have the code editor also for smaller blocks, at least for columns and not only for sections
have more specs for flex positioning, you give flex positioning, but where are all the other properties?

Bug?
When I create a custom module or a core joomla article with the page builder, sometimes the button for saving or closing the layout remains frozen (but the save is still done).
Another annoying behavior: saving from custom module or core joomla article makes me go back to Joomla interface instead of staying on page builder interface.

Question
Why if I create an article directly with your page builder the settings tabs like "Images and Links", "Options", Publishing", ... are not available?

Many thanks,
Lorenzo
