1) Please make the Electric Sorting Machine compatible with the pulling upgrade. This will allow pulling from non-IC2 machines. Currently the only way to do this that I know of is buildcraft pipes.
2) Would it be technically possible to allow for more item filters on each side? More would be much better.
3) I know it's called an electric item sorter, but some way to use it without having cabling connected to it would make it amazing (an advanced sorting machine, maybe?). I find an electric item sorter is the best way to evenly distribute work across multiple machines. However, in most cases i have an input, output, and cable, that leaves me with a max of 3 machines that I can distribute among. I can add an extra machine by coming up with a system where the input and output are the same side, but that gets really messy and ugly. Freeing up an extra side would make things much neater.
