In the Actions aspect, I see the AST root node Smart Editor Actions, but I when I look in the code base of the MPS platform, there is no example of this type of action. This makes me wonder this this type of action root node is still meant to be used by end users in MPS 3+.
Furthermore, once the root node is created, the 'surround with actions:' section provides no way to add anything in the attribute. Again, this suggests the action is there mostly for backward compatibility. If that is the case, should this action be marked as deprecated?
If it is useful for something, where can I find an explanation/example of what it does? Thanks.
