Good addition! Do you think you can add a test case that covers it?

[rubenporras]

this is indeed a nice feature. Without going into the details, my company has setup very specific dialogs for creating files in the workspace, and the usual create file dialog is not usable.
Do you know if this PR will always open the default create file dialog or if it is configurable? If it is always the default, could we make the new feature optional?

Glad it please you:)

I fear that it can be hard to write test since there is a message dialog which is displayed. I never written this kind of test.

If you see the demo, you will notice that there are not some create file dialog, just a confirm dialog which ask to the user if he want to create the file.

OK. Let's merge as it and cross fingers it doesn't regress later. If it does, then it will be a more motivating opportunity to write a test.
