User often has to scroll the frame under 'Composite Navigation' buttons to see names/values (e.g., java.lang.GarbageCollection.Copy -> Attributes -> LastGcInfo). Not very convenient.

I think there is a solution. For example, Name column in to Attributes tab is usually is too wide and has a lot of empty space unlike the Value column. Another solution is to place the frame to the bottom of the attributes tab or make it a floating window, etc.
