Wow... I didn't think this thread would continue, but since it did I will throw in my two cents quick about the "bug" debate...
To me, this is a bug, since the header (which I never altered in any version of SONAR) in previous versions included those buttons. In X3, of course the left edge now has the ability to custom color the track (great enhancement), and it is about 20 pixels.... BUT... I only needed to scoot the right edge about 3 pixels to get the buttons back. So, I assume it was "accounted" for, but not correctly (i.e. the right edge WAS scooted automatically, but 3 pixels shy of the mark to make it transparent to casual users like myself).
The bigger concern for why I consider this a bug is even simpler... if a user opens up a piece of work from a previous version they spent hours (or more) to create and their first reaction is "Where is everything I had here??" That is VERY bad. Impressing the end user is good, shocking them is not so good.
As far as "criticality" of this bug... it is LOW, I agree, but I think it was not "intended."
