I realize that the color change option offers a very nice visual but only option 4 controls the trend buffer.  I respectfully request either an ADDED trend buffer sayyyy maybe 14 or re-setup 13 for option1. 
I have several of your indicators with 2 & 3 trend buffers, One in particular, 3ma-3.03, I use a lot. So am I asking for something unattainable or is this indicator of a peculiarity that it can't be done. 
I apologize if my request was of such a scrambled nature as to confuse the request. 
    cl_slope, // Change color on slope change  -0
   cl_sign,  // Change color on signal line cross -1 I respectfully request either an added trend buffer sayyyy 14 or use 13
   cl_mid,   // Change color on zero level cross -2
   cl_inc,   // Change color on inner levels cross -3
   cl_out    // Change color on outer levels cross -4 controls the buffer 13
Thank You
