Hello, recently ghemical-2.00 was released, so that in future we will both add minor fixes in ghemical-2.0x series, and also develop new stuff. However, my opinion is that ghemical already is a rather large program, so I would rather stabilize and organize better what is already there, rather than add new features. So, in that sense "undo" is not at top of my list. Also there were questions about molecular mechanics features (partial charges and pi-conjugation). I also have to say about them, that trying to add a new force field or trying to do a major improvements on existing ones, takes a lot of time. Right now I have to spend my time on my PhD work, but I hope that after a 12-24 months period the situation is better. Regards, Tommi
