What I like and consider user friendly software is when you use something for the first time a dialog box pops up asking for your preferences and then this- A check box that say's "don't show me this again" There you go, set and forget.
Sonar doesn't always remember your preferences, My bone of contention is new projects no matter what default to Comping. I always have to remember to change that to Overwrite.
On the topic of reading, I myself have always been a "reader" of manuals. But it seems we have the new generation of Visual learners who I guess after being weined on Video games prefer the Video tutorials. I find the videos are too slow paced and so it takes longer to find that one "paragraph" I needed.
