Describe the suggestion
I would suggest you make Augments be able to behave like Barrier Blocks. If you hold the item in your hand, It will be visible on the track. if not, it will be invisible. This could for example be achieved by shift-right-clicking the augment (e.g. a Detector) with a glass block or similar.

Applications of the suggestion
Hiding Contacts near Platforms

Augments are slated to be replaced and I am not planning on making significant changes to them at this time
