Struct OverlayConfig 

pub struct OverlayConfig {
    pub polygon_sides: u32,
    pub grab_tolerance: u32,
    pub loupe_radius: u32,
    pub flash_ms: u64,
    pub flash_brief_ms: u64,
    pub caret_blink_ms: u64,
}

How the overlay feels: reach, magnification, and how long it talks.

None of these change what is saved. They exist because the right number is a matter of hand, screen, and eyesight rather than something this project can pick for everyone.

Fields

polygon_sides: u32

Sides the polygon tool starts on.

The digit keys reach 3 to 9 because that is what one keypress can say. This is how you get anything else: set it here and the tool opens on it.

grab_tolerance: u32

How close to a border counts as grabbing it, in logical pixels, scaled per monitor. Larger is easier on a trackpad and makes small shapes harder to click inside.

loupe_radius: u32

The magnifier’s source radius: it shows a 2r+1 pixel square, so larger means more context at less magnification.

flash_ms: u64

How long a message stays on screen — saves, errors, the things worth reading twice.

flash_brief_ms: u64

How long the brief messages stay: tool switches and the like, the ones confirming something you just did on purpose. Raise it if 1.2 seconds is not long enough to read comfortably.

caret_blink_ms: u64

Caret blink interval in the label editor. 0 stops the blink and leaves the caret solid, which is a supported value rather than an accident of the arithmetic.
