It would be very useful if refactoring actions such as declare member variable, implement interface/abstract class etc. would take into account the relevant ts-lint rules. At a minimum the following rules can be enforced:

• member-access - add explicit public | private modifier to newly generated members
• member-ordering - add the members in their right place (for example public fields after existing public fields, methods after existing public methods etc.)
• promise-function-async - automatically add the async modifier.
• quotemark - use the right quotes/single quotes for automatic import declarations

As a small side note implementing abstract base class refactoring should also add automatically the async modifier if it exists on the abstract member.
