I have a heavy InDesign background as I used it professionally for a number of years. (CS 4 and CS 5, back in the day.)
I recently opened up Scribus again to see how far it has come. (Last time I used it I found it extremely unintuitive with much missing functionality.)
One basic task I was hoping to do easily in Scribus is to visually lay out text on a page. For example, put a header on a page in its own text box and then scale it visually to the size and width/height that I want. In InDesign, this is easily done by holding down a key (I think it's Ctrl) while dragging the edges or corners of the text box, which makes the resizing apply to the contents of the text box along with the text box itself.
I tried Ctrl, Shift, Alt and various combinations thereof in Scribus (version 1.5.5) but couldn't produce this result. I searched online for "Scribus scale text" and "Scribus resize text with frame" and found nothing useful.
Is this even possible in Scribus?
