I see you commented out the second half of the mod.

Was that needed for 2.0, or did you just not like that?
I note that the icon for it is still in the thumbnail (well, it is the original thumbnail)

Thanks for updating it - I miss Kitch.

Module adjustments? that commented out section is for the ghosting notifications when you place a blueprint.

It was a blue triangle icon indicating that modules are missing. Look at the mod thumbnail at the blue triangles.

ItemRequestProxyPrototype 'item-request-proxy'
Entity used to signify that an entity is requesting items, for example modules for an assembling machine after it was blueprinted with modules inside.

2.0 did change how missing modules are displayed, so not sure how the original code would look without testing it..
