Feature request. Multiple 74hc595 linked directly with raspberry pi

1)I mean raspberry pi has 8 pins. So at least you could allow to connect two 74hc595 directly to raspberry pi but your library has only 3 predefined numbers. Why? They will work faster.

2)I don't know if it is possible in general but... Let we have 74hc595 connected directly to raspberry pi. So we have 2 pins left + each 74hc595 may produce 8 pins: 2 + 8 * 2 = 18 pins. Could we force them to produce even more pins: 18 / 3 * 8 = 48 pins?

1. Thats the whole goal and precisely how a shift register, as 74hc595, works. Look it this way, you load the n-pins in series but when latched the values are transfered to the outputs in parallel.
   I managed so far to connect 4 registers in daisy chain.. looking forward for 8.
