I would like the ability to be able to use design components such as lines and callouts on a modal layout. I would use the callout to add instructions for the user and the lines would be to just add a visual breakup between columns.
This would be a very handy feature!
Yes, would be very useful too to have the ability to add section and title of sections. Currently, I’m doing it by cheating a little bit but I think that can match your need.
Titles circled in red are always the same and I’m using it + some line breaks to have a visual break.
