??? Why a Injector Upgrade... what type of use ?? that you can not already do now ?
Compactier setups so you don't use the inefficient hopper to insert items and pull items/fluids from other machines/tanks (that are not from IC2).
Quotehopper to insert items
..look IC2 Item Buffer
Quotepull fluids from other machines/tanks
...look IC2 Pump
Quotepull items from machines
... ok missing but only use a see is to pull from chest all IC2 Machine have Ejector Upgrade Slots
+1 the idea
What cool designs are you thinking that we can't already do? Past spreading some existing ones out, I can't imagine many.
I still think it would be good, giving the player more options may create something new.
The import function would be especially good when dealing with non-IC2 blocks.
That's true. It's funny how suddenly an IC2 only world could actually work with things like liquid and item transfer.
how does one use the item buffer? it seems like it has a specific way but i don't understand
That question might fit better in the support section :3, and i don't know either 
What is situation with this suggestion? is it considered or rejected? I would really like and need this upgrade 
From my point of view neither accepted nor rejected.
I'd like to see it become true actually, it would help people on automation setups.
An example usage would be a highly overclocked macerator next to two chests, quickly pulling items from one, outputting to another.

use a ejector upgrade and select which way it should output!
IE if
you want it to go up out the top of a buffer then have the upgrade in
your hand and right click on the bottom of a block and it will always go
there !
this way you can setup a mini refining station for ore to bars!
as you can see i have buffers to put stuff in.. they output to the macertors in the back into a new buffer to wait and be washed! then what comes out from there gets sorted ! or bits dust get sent to the top two boxes .. the ore gets spun and its outputted to the furnace up top
washers have a pump next to them to refill from a unlimtied water source!
bottom buffer / box on right side is a compresser for bars/ore bits! ( not automated)
centerfuges use there own power source since they use so much it was causing power loss for the others at times..
(attachement is the pic but i can't figure out how to get it to show better?)
