Thanks,
Those technic groups are part of the 'sorted' (sorted by function) bin tree branch, accessible through the very first icon (little groups of parts picture) in the root group.
Part snapping is available since the 1.3 version, although it's more a guidance tool not full blown collision detecting etc. But it works quite well when used in combination with the relative grid.
You can enabled/disable it from the compass (GS/PS at the bottom) at any time or by using shift+p.
Do note not all parts have snapping info yet, currently I'm working towards having info for all parts in the sorted branch of the bin which is almost done having only a couple of subgroups remaining.
