Text/Font size displayed when shrinking/enlarging text. Sometimes hard to get text uniformly sized over the breadth of the canvas. Would be nice to have a text or font size displayed in the text edit box showing some marker of the selected text size, either absolute or in relation to some other text in the prezi.
If you resize text, it will “snap” to the size of a nearby object (make sure both objects are visible).
In addition to gparyani’s suggestion, you can use copy / paste / duplicate (ctrl+c, ctrl+v, ctrl+d) to copy the font size, and then change the wording.
These features are also available on the right click menu.
