Feather Plus is a lightweight Blueprint Function Library (QoL) that simplifies everyday Blueprint work**: the math and debug nodes you keep rebuilding — without another 200-node kitchen sink.

It sits beside stock Blueprint nodes. About 155 helpers in six categories: Scalar, Vector, Rotator, Random, Compare, and Debug.

Scalars: Negate, NAbs (force non-positive — not the same as Negate), Abs+Sign, round/snap/truncate, percent, inverse lerp, map range, wrap/ping-pong, safe divide/power/sqrt, approach / Smooth Damp / exponential approach, invert 0..1, bool↔float, threshold select, min/max of three and over arrays.

Vectors: clamp, project/reject/reflect, distances, segment closest, angles, safe direction, cone random, flatten axis, approach.

Rotators: shortest delta and lerp, clamp/snap/normalize, quat-combine delta, yaw-only look-at, random ranges.

Random / Compare: chance, streams, biased ranges, stable seeds from String/Name; three-way Less/Equal/Greater (pure + multi-exec branches); nearly-zero tests.

Dual API on transforms: Pure Out, Callable (Exec) for mass/loops, In Place (Ref) with no Return pin — one shared C++ core. ToolTips explain Pure re-eval vs Exec.
