Changelog

1.1.0

The key now switches Extra Snap Points Made Easy off completely, not only its extra snap points: its snap modes (Manual, Manual+, Grid) and their keys stop working, and its key hints are hidden, so the game snaps exactly as without the mod. Pressing the key again brings everything back.
Every press starts snapping over: Extra Snap Points Made Easy returns to Auto mode, and the snap point picked with the game's own Q / E is reset to automatic.
The config setting HideExtraSnapPoints is renamed to ExtraSnapsOff; the saved state starts from "on" once.

First release: a key (F7) that turns the snap points of Extra Snap Points Made Easy off and on while building. Works instantly and on pieces that are already built.
The current state is shown in the building key hints and remembered between sessions.
