I had thought about it, but I found that in practice that the majority of applications I send out wind up in the 'Applied' state and don't get much further, leading to a large list in a narrow swim lane.
That and I am able to customize the flow of applications, and the number of swim lanes would be a bit messy. I have my app setup to track interviews, phone screens, take home assignments, and many more.
I found that a smart sorting algorithm is best for displaying the applications.
But its still early days of the app, possibly someday.
