Currently debugging applications from Qt Creator is difficult as tarnish needs to start the application, which means you can't attach to it.

Describe the solution you'd like
One of two things should happen:

1. Somehow allow starting applications under tarnish in a way that gdb can attach in Qt Creator
2. Allow applications to register themselves on startup with tarnish so they can be started directly.
