@G81192 can you provide more information about this approach? I'm thinking maybe it shouldn't be called "getOrOpen" if the create functionality is added. Maybe we could call it getOrCreate or something, or make the flow more clear. I want to make sure we're not creating files when we shouldn't

@RomneyDa Thank you for the reply.

The issue I'm encountering is that, with the current unmodified code, when I try to create a new file generated by the LLM by clicking create file, nothing happens. Instead, the file currently open in the IDEA window gets modified.

After looking into the code, I found that the getOrOpenEditor method returns the currently selected file as the editor when the target file does not exist. However, in my case, I need to create a new file — and since it doesn’t exist yet, this results in an error.
Example:

1. I want to create the file:
   

2. When I click create file, the currently open file in the IDEA window gets modified instead, which leads to an error:
   

3. This is the expected behavior I want to achieve:
   

This PR is intended to fix this issue. If anything is unclear, I’m happy to provide more details.

Hey! Just wondering if there's anything holding up the merge — happy to make changes if needed!

I would +1 Dallin's feedback, I think the existing method should be left as is and instead we create the file in https://github.com/continuedev/continue/blob/main/extensions/intellij/src/main/kotlin/com/github/continuedev/continueintellijextension/continue/ApplyToFileHandler.kt#L172 when we realize it doesnt exist. I don't think we always want the side effect of creating a new file in getOrOpenEditor
