Inconsistent use of particle index when inspecting particle
The ParticleIndex property is 0-based. However, when using the "Inspect particle" tool it is e.g. for the particle with ParticleIndex=0 the text "Particle index 1:" is shown. This is somewhat confusing, especially when first using an ExpressionSelect to pick an atom with a specific index, only to see a different index in the particle inspector.
