Road map of Fabric development

waveform display:
- display write head
- display play head
- move write head with mouse (when stopped only?)
- move play head with mouse (at all times, relative only - no jumping)
- show spray amount visually
- spray offset amount (-1, 0, 1)
Volume control:
- in volume (dry)
- out volume (wet)
- out mix control
Buffer controls:
- rec active (button)
- overdub active (button)
- clear bufer (button)
Grain playback control:
- Density
  - Option to adjust Density in Hz or Beats
  - Possibly have two seperate controls, and allow syncing between to allow ramping effects
- Readhead speed (-5x, 5x)
- Readhead sync to writehead (to use Fabric as a set'n'forget effect)
- Readhead sync to writehead offset (as above)
- Grain length
- Grain Pitch Spray control
- Grain Pitch
Stereo image control:
- Pan spray (L & R)
- Stereo Width
Grain Envelope controls:
- Sides (taken care of with Tukey window function)
- Tilt (moving apex left/right)
- Curve (move from a convex - straigh - concave shape)
Grain direction:
- forward
- reverse
- Implemented as direction forward/reverse factor
State:
- Save/Load the current content of the audio buffer to a wav file
- Import wav files of different lengths
  - Read first 10 seconds, or allow user to move the audio file if longer?
- Save the audio buffer state when record is off
