Currently in WebStrom we have only Before launch section that can be populated with some tasks.
It would be great to have out of the box possibility to have configurable After execution section as well.
My use case is very common: Launch data server, run unit tests that take data from this server, stop data server.
I believe that many developers have/will have something similar going on. And without this feature we can't be very comfortable with IDE as we need to mange some other processes to conduct debugging.
