Currently, when you open the GUI, the search function is auto highlighted, meaning you have to press the escape button to get out of the GUI. This can be improved a few ways:

• Make a button on the side (like AE2's terminals) to change between search modes (standard search, auto select, etc)

• Don't force auto-select when you open the GUI (so you'll still have to press escape to leave the GUI if you select the search bar, but if you don't touch it you can just press E)

Maybe a way to see the Mass Assembly Chamber from a terminal?

This suggestion is more of a "if it's possible it'd be cool, but it sounds difficult to implement" so feel free to ignore it:
Allow scroll wheeling through pages of recipes. Because clicking through 40 pages of recipes is carpel-tunnel inducing.

Obviously, all of these are my opinions, but I feel they would make your mod even better than it already is.
