In MS word or Google Docs, we have a format painter that takes a sample of the format of some text and can apply it other text. Now, this becomes much less important when we use styles (in Word or Docs), but it's still handy and it would be in Webflow too.
For instance, if one of my sections is becoming too big and I need to turn some H1 headings into H2 subheadings it would be nice to be able to turn one into an H2, then copy the formatting with the brush and, with one click on the remainder of the headings, turn them into H2.
