Ok, I've searched a bit and think I've found some partial answers but I need further clarification:
Basically I have a filled polyline, three lines of text that make up a logo. If I drag a selection box (using the move tool) over the elements, I end up with the usual group selection with grips/handles on the corners and centres (as well as the rotation handle above the main selection box). If I then click and drag a corner, the selected elements move to a new position relative to the original start position.
What I simply want to do, with my mind firmly stuck in CorelDRAW mode, is to resize the group based on dragging a corner out, expecting the font size of the text to increase/decrease accordingly.
I've tried using the node tool and that doesn't offer the handles on the corners of the grouping box.
What have I missed?
