I have multiple vias for which the track exists under the annular, but has become disconnected from the via.
Is there a function which connects selected unconnected-tracks to the nearest (same net / no net) pad/via, such that I do not need to visually inspect and manually snap disconnected tracks (as occurred here)?
DRC will catch these unconnected wires, but you will have to fix them manually. KiCad does have an f hotkey that attempts to finish routing of a track. Placing the mouse cursor near a via and then pressing xf may be sufficient. X starts the routing, and f connects it to (I assume) the nearest open track or pad. It is one of the newer functions in KiCad and I have not used it much yet.
