1. Open a project in Qt Creator.
2. Place a breakpoint in the project.
   It will help if the program will run a while or wait for user input before hitting the breakpoint.
3. Run the project in the debugger.
   Creator will switch to Debug mode automatically.
4. Switch to a different mode, e.g. the Projects mode.
5. Let the debugged program hit the breakpoint.
   Creator will show the code line at the breakpoint. For this, it will switch to Edit mode.

Instead, Creator should switch to Debug mode in this case. When hitting a breakpoint, users will probably be interested in the Debug mode's specific views. They might also be confused that the debugger controls seem to be gone.
