Greetings from Australia. 

I use ChimeraX animations to teach elementary school children how food is converted into the CO₂ we exhale, so:

B) is there any way to display double and triple bonds? And, if not, are you planning to add this feature in future versions?

C) apologies for repeating this question - originally asked by Chase Smith (28 November 2019) - but I couldn’t find a response

Many thanks in advance,

Ruben
