This is a different kind of analysis. Avogadro 2 does have full point group symmetry analysis (e.g. New symmetry features in 1.94)
QTAIM is Bader’s Atoms-In-Molecules analysis. It looks at the quantum chemical electron density to find bonding interactions, lone pairs, etc.
The code is pretty much identical to the v1 version: Using Atoms-In-Molecules (Bader) Analysis - QTAIM and WFN - Avogadro
