+ drone is anchored or launched on creation
    anchored means stays fixed at the place of creation
    launched means 'flies' off based on its velocity and gravity
      try with Menu > Drone Tools > Add / Wand
    set at Menu > Drone Params > Defaults

+ set velocity +/ acceleration vectors of drones to presets via Menu > Drone Params > Motion > Set velocity/acceleration
  + presets are +ve or -ve vertical, horizontal, velocity, acceleration and zero

+ auto flip (clock < > anti-clock) auto rotating velocity/acceleration vectors every some degrees
  + via Menu > Drone Params > Auto flip > Set / Unset / Toggle
  + default 'every some degrees' is 90 degrees

+ gravity
  + presets for gravity vector
     0, left, right, up and down
  + gravity tracks mouse position
    + click Gravity > Mouse
  + gravity tracks the first among selected drones
    + click Gravity > Drone
      ! as drone selection changes, gravity may track a different drone !
    - removed Menu Drone Params > Track gravity

+ mesh polygon filling per drone color

* color of a launched drone is same as color of the launcher
  * try changing color of the launcher as drones are launched

* changed color of velocity/acceleration vectors to move away from green (used for selection) and red (used for errors)
  * cyan = color of velocity vector of all drones
  * (reddish) magenta = color of acceleration vector of all drones

* changed arrow visualisation of velocity +/ acceleration vector of all drones
  * Head
    * edit the position of the arrow tip
      * can go 'above' the vector tip ie > 1.0
      * can go 'below' the drone location ie < 0.0
      * can be on the body ie 0 <= tip <= 1.0
  * Shoulder Position
    * edit position of the arrow's shoulder tips
  * Shoulder Width
    * edit width of the arrow's shoulder
  + Cap or Decap the arrow

+ set default arrow head, shoulder position and width, cap from Menu > Drone Params > Defaults
  + used when adding & wanding drones
  + change existing drone's velocity/acceleration vector arrow params via Menu > Drone Params > Visual

+ improved geometric chuck
  + on a chuck with N drones, the first N - 1 drones have trail set to 0
    + the last drone has trail set to 10000
  + toggle auto reset trails
    + Menu > Drone Params > Chuck > Auto reset trails
  + 2 changes above aid visualisation and experimentation instead of manual trail
    resize/reset every time after changing a chuck param
  + toggle chuck outline
    + click Menu > Drone Params > Chuck > Draw chuck outline
    + aids screenshotting
  + chuck outline drawn per drone color

* default scale/rotate drones center to microtonal keyboard center

* default selected range to C Eb

+ mouse wheel on microtonal keyboard to scroll along horizontal
  + press SHIFT and scroll to scroll along vertical

* short form of echo command is .

* improved bpm handling of drone pendulums and meshes

* improved drone trail handling/display

* close menu after setting modulation direction

! fixed bug in zoom of curve editor when mouse slider is active !
! fixed draw crosshairs on drone mesh preview !
