Oh believe me, Adobe Illustrator could be VASTLY improved. Does anybody remember Macromedia Freehand (RIP)? Adobe brought it and then killed it. Now they have no need to improve illustrator – which still works much the same as it did in it’s ‘glory days’ (which would be about 1993 if memory serves correct.
In summation, the final version of Freehand (2002) was much better, easier to use and more intuitive than any version of Illustrator produced.
