I just tried to create a new session without making any changes at  
all.  I suppose this is an unreasonable assumption at this point, but  
new users will expect thing to "just work."  (I've been using Ardour  
since one was required to compile a kernel in Linux form scratch but  
not everyone will want to deal with any hickups.)

All available physical channels on my 2408 is 24.  Only 8 showed up.   
You do have a valid argument for not configuring however.

I noticed initially that scrolling though the file system while  
importing audio is extremely slow.  One flick of the mouse wheel and  
I had to wait for the screen for a while.  Also present in adding  
LADSPA plugs.  When recording, the edit window was very slow to begin  
drawing waveforms - so much so that I made a double triple take to  
see if it was rolling.  Record-enabling tracks was quite a wait as  
well.  FYI, my video card is the original that came with the machine.

Also, apple-M bring up the mixer window but resizes it and places it  
in the upper left corner.  I had the G-verb gui open and it was  
kicked up into the upper left corner as well.

Apple-` doesn't work to scroll through window.  (I think someone may  
have noticed this already.)

Think how pretty it would be though!  ;)
