Only tested on PPC, please confirm if you experience the same problems:

- as you say, painting is pretty botchy ATM
- [S] to change the "strength" value doesn't work
- set "strength" to 1.0 by default, since changing mode from linear to 
long/bended/s-shape should immediately change the shape. (As long as strength 
is 0, all modes are linear)
- the <E> dialog has no functionality anymore, so we should get rid of it
- the cursor should not move while changing values, because it quickly leaves 
the fade area, which feels confusing (mainly if the it enters another fade 
area).
- it should be more robust in critical situations:
        - if the clip becomes shorter than the fade, the length of the fade 
should
          start to shrink (the upper fade points (at 0 dB) should never lie 
outside
          of the clip)
        - fade-in and fade-out should not be able to overlap (see fade 
attachment)

I never had a problem with [F G] and [G H], but [F] seems indeed more 
consistent.

I would say it should follow exactly the movement of the mouse cursor. It's a 
bit hard to make long fades at the moment.

And while we're at it: I would prefer if dragging edge behavour would be a bit 
different. See attached edge1.png for an explanation. Any comments on that 
suggestion are welcome.

Best regards,
Nic
