We just uploaded a video showing off the new template tool, building up triphenyl phosphine oxide.
You can easily add atoms with specific geometries, and click to add functional groups.
We include over 150 with 2D previews. Suggestions always welcome:

Tested out some water clusters during lunch.
- MMFF94 has point charges and hydrogen bonds
- UFF does not (so water molecules push apart)
At some point I'll add some simple dynamics…

Thanks to a suggestion from a user, we've been working on some tweaks to the draw tool...
Now you can click on a hydrogen atom to change the element and the bond will grow longer or shrink as needed
Coming soon to the next release (or in a nightly build)

As someone who went to grad school as an inorganic chemist, it gives me some pleasure to finally have a free tool to click-click-click assemble iron bipyridine complexes or Ziegler-Natta catalyst models in @avogadro.cc in about the same time it takes to build an organic compound. #chemsky 🧪
