The biggest problems for me are:
1.) audio-clips aren't cuttable
2.) clips aren't slip-editable at their beginning
3.) it is virtually impossible to fade the audio-material when you are working with a longer recording/sample without using an envelope.
It is not possible at all to do it quickly.
4.) a bug results in that a wavefile that is longer than the clip it resides in sometimes still gets displayed on the timeline (sometimes depending on the zoom-level

If you think these issues (and probably other related ones) are really important this is the right place to tell it
(even if you did before)
