- Start Creator with clean settings.
- Open an existing project.
- Close the project.
- Select "File" -> "New File or Project..." from the menu.
- Select a project template and click "Choose...".
For creating the project, Creator will suggest the source directory of the project from step 2.
I think this is wrong because it might mess with completely unrelated projects. I'd prefer using the parent of that directory or even the user's home directory.
