It’s highly configurable you can choose what WordPress files you want on all your WordPress sites and what you want to store separately from each other WordPress … Read more
The answer is mostly no. The “enhanced” text widget was designed to work like the post editor as much as possible, including autop which might break whatever HTML that can not stand the conversion of lines into paragraphs.
