Wouldn't it be more productive to replace the dropdown menu of the text, image etc alignment in the builder with the classic icons for left/center/right/full allingment?
Speaking of UI improvements every number field (font size, image size etc) should have the little arrows for up and down and respond to mouse wheel. Some fields do right now but some dont and it feels like an oversight.
Also the default 30px of margin bottom on every pluggin. It would be nice if there was a field in the settings where you could set it to another value for all the site.
Finally some design elements seem too bulky. Things like checkboxes or switches would be a lot smaller and more streamlined.
I've been using SP page builder PRO for 4 years now and I believe that moving forward such changes would go a long way.
Thanks for your time. :)
