Awesome work again, I made one last small change on the WelcomeWindow fixing an issue related to opening files/folders from the button.

Again, thank you for doing this work!

@thecoolwinter Should we wait for a formal release of the WelcomeWindow package before merging this?

I made a v1.0.0 release tag there, this does reference the main branch. I could quick change that if you think it's necessary.

Yeah, if you wouldn't mind. Feel free to merge after
