First of all, it works perfectly for what I wanted it to do, but while configuring it I found a few things that could be better. We did this one early in development and it kinda shows.

1. Later on for the tubes we color-coded the cardinal directions to make it easier to configure. The Redirector should use this, also. I propose a small indicator on the texture of the master on on each side that can be seen that is grayed out/colorless unless you put a slave for that direction, then it lights up in the color of the direction the slave is, as well as some part of the slave that lights up in the color of the direction, maybe a circle around the output, or a design on the machine block. Then also add the color to the gui text and you can configure by color instead of having to figure out if you want the energy going south or north. If you need me to, I can make the textures for it, but it would be better if someone that is actually good at this takes a look at it. I also added a picture below hopefully showing what I have in mind. The textures for those blocks are so basic, a direction indicator might actually make this look like a nice feature if you use it in a base, instead of something that is just in the background

2. Add a way to set a default direction. When I configured this I had to play around with it for a while to get figure out the % one side needed, and it got annoying pretty fast that I had to substract what I added to one side from another. I propose you can set a side as default, either by using the same button element we see on the tubes, or by having a button next to each input field to set that field as default. Then, when you end up having less than 100% distributed, it would automatically add the difference to that field, and if you have more distributed, it will remove the difference from there, at least if possible. That would make configuring this way easier.

@Daenara we would need some art from that. Otherwise this is closed... And I am pretty sure @jawsawn or @LuxOperatur don't have time/interest for it...
