gbfe:

* clean up that horrendous abomination you try to call 'code' for
  the Smooth/Angle menu --- sheesh.
* have a function bookmark list
* why is there a sigsegv when you click the 'X' button?
* functions: list of common, history, possible keyword names for functions
  - see functions file in this directory for a suggested hierarchy of functions
* option to create image with name of child pid in /tmp.
* series, generate images with variable, step value
  + 12 images, from x to y, so step y-x/12 ... blah blah
* read/save .rc file with your prefs
* color palette editor

bfe:

* have the png saved at the color-depth being used
  right now 'palette' is only an 8-bit palette, no reason
  to save a 24-bit PNG.
  - palette is not a palette in the sense that it is a color lookup table
    containing a fixed number of colors that is indexed into by each pixel.
    think of it instead as specifying the endpoints of a gradient.
    bfe currently supports four different image types, given by 8 or 16 bits
    per channel, and 1 or 3 channels.  This gives us 8 and 16 bit greyscale, 
    and 24 and 48 bit color.  8 bit color would be a pain in the ass.
* more color options
  - iteration based method needs work.
