You do here global settings, which are independent from the selected mode.

size of cell
size of the cell on display. value is between 2 and 7.  2 means a cell gets 2x2 pixel, 7 means 25x25 pixel. The smaller one cell, the larger the amount of cells to compute. This may slow down the programm dramatically.
Speed of computing generations.. value is between 1 (very slow) and 8 (top speed) .
max. random
for setting cell state by random, the cell gets a value between 1 and max. random. 1 up to 9 are valid.
edit colour
By drawing on the screen the new cell/pixel gets this value, respectively the colour matching this value. 0 up to 9 are valid.
