Hello, I would like to see that PRTO can pass there patricles to pipe's, Pipe can release there particle's to PRTI but with PRTO you need an empty space between wich reduce the speed of flow with a huge amount. (If you use 1pixel pipe's)

I dont know if its possible but mayby give PRTO the same property of Stor to pass the particle's to pipe's

It would also be nice to deco stuff becuase you get rid off empty space's
