Hi, thanks for making this one, it's the perfect balance between Factorio aesthetics and function!

There is one feature I feel it should have, and that is activating Alt mode overlay over a configurable area rather than only at your cursor.
Why? So when you're setting up a build, eg the usual 5 assembler green circuits buid, you can see all the recipes and modules as you're building it.
This would also work when you're looking at a single assembler and filters on attached inserters and contents of chests are also made visible.

I also feel this mode should be default with, say, a 6-8 tile radius around the cursor. What say?

Hi. I’ve realised this is a problem too, which is why I’ve added Auto Alt Mode (which can be enabled in the settings). This automatically switches to ALT Mode when you’re holding blueprints or wires (pipes are also planned).

I’ll have a look at your suggestion. If it’s feasible, I’ll implement it. It might take a while, though, as I haven’t had much time for modding at the moment.

I've reviewed your suggestion. Unfortunately, it would require a major overhaul of the mod, which I'm not willing to do. The mod is already insanely complicated. So, I'm afraid I have to turn down your suggestion.
