This is a multi-part idea but it'd be great if the text layout tool would let users
(a) Insert text specifying a position in the middle / center of the text
(b) Autoscale text to fit some constraint (user draws a rectangle and asks that text scale to fit and the appropriate scaling is chosen to ensure that the text fits both the length and width of the box)
(c) Support for text kerning (it's easy enough to do that in Illustrator but user adjustable optical / metric kerning would be very useful for quick logos and for people who are just **** about how their text looks)
(d) Much better text rendering support (ideally any vector system font should render to and the outlines should be as smooth and continuous as possible; this is an extruded «s» in Arial)

(e) Simple drafting on extrusion of text that works (lots of manufacturing processes need some draft on extrusions but if you type something and extrude it with taper (read: draft) now, you get something like this even if you set the depth to 1mm and the angle to, in this case, 0.001º)

You can extrude without taper and then manually add draft, but then you have a nightmare of selecting countless faces as in (d)
Aside from the above, it'd be great to talk with a graphic designer who knows text and fonts, and have them walk you through the stuff they use in something like Illustrator or Page Maker.
