Since CAS introduced their new non-Java structure editor last month, they have already added some new features:
- Reaction arrow tool
- Undo/Redo with complete cycle of undo/redo actions
- Chain tool
- Structure drawing preferences for fixed drawing length and angle
Also improved this month: display options for answers/page and full/partial/no abstracts are now in a pop-up menu that comes up when you click Display Options.
