A big screen where you can see different information

What information?

For example what the system craft or the energy in the system

You can see what the system is crafting on crafting monitors, and you can build a display for the energy in the system. I think thats more fun then just "giving you one"

Hm, i have an idea! It can render structures from Spatial Storage Cells.

rendering a huge section of another dimension is not sane, it will mos likely be very laggy ( lots of extra data ), and buggy ( advanced rendering is always a pain ).

All these features on one screen can be a good thing

UP

DOWN

This sounds more suited to a mod like computer craft, the power thing you can already build, I'm and the only other thing you have suggested so far was "crafting status".

It can tell you how much time left before the craft is done

AlgorithmX2, you could do 2D rendering, that's easier and less laggy... and less helpful

Yes it's more easy

Time would be an estimation, and would be very inaccurate, so I don't even want to try it, that would be a map... and pretty pointless.

Bigger/multi item storage monitor?

Pretty sure you could just build that. This suggestion is lacking in... meaning, i'm just closing this.
