I wish Shift+enter inserted a line break on the canvas, not a paragraph break

H1 style is a great way to highlight numbers or to put big emojis on the canvas and create some nice visual hierarchy.
And sometimes I want to create a two line heading for greater impact. But the space below h1 paragraphs kinda separates those two-line headings too much giving the idea they’re not related.

I expected shift+enter to create a new line without that spacing — like other softwares like google docs or adobe InDesign do —, but it produces the same effect as typing “enter” (in other words, I expected Shift+Enter to introduce a new line, but it inserts a whole new paragraph)
